TBH the real strong points of Go are: - single static binary (the EASIEST for deploy) - simple language (few keywords) - cross compiling is as easy as set GOOS and GOARCH - Pretty decent performances (not the best, not the worst) - MOST of the stdlib has consistent behavior - MOST of the 3rd party packages have consistent behavior - Simple and effective package manager - Perfect fit for backend services, literally, it is perfect - Absolutely perfect retrocompatibility (Rust, Python and TS haven't guaranteed it even with minor or patch version) About dev velocity: i have spent a lot of time time dealing with TS, npm errors and stuff. By that time, i finished two services in Go. That's subjective, but a consistent ecosystem is a great value to me.

the single static binary is a killer feature that is underrated. currently working on something interesting where we're trying to tackle the "better than WordPress" problem where WP is so easy to install that non-tech can reasonably deploy their own instance of WordPress. Go is the strongest candidate as it compiles into a single portable binary, but it can also carry contentful stuff (like JS files, images, and many others) in its binary. So, a Go Binary program effectively becomes runnable zip files.

technically they do some breaking change on the stuffs with buggy behavior (fixing, to be precise). Yes, no one should use those buggy behavior anyway, but it also mean that you can't carelessly update the project without some checking where external package might use that thing.

Go was literaly our only option. We use Go with AWS Lambda and is not only about CPU performance but RAM usage, even with Bun, JIT and interpreted lanjuages like JS and Python can't handle 1M+ records in a 256mb RAM container, even Java or C# have a memory overheat due to their VM. So basicaly Go was our only alternative to cheap microservices with a good support for AWS SDK and low learning curve. Also, cross-compiling works great, since we use ARM based Lambdas, reducing the cost even further, all in just a 10 - 16 mb binary.

It definitely helps with cold start times, but it's still real chunky in terms of binary. I don't remember how memory consumption compared though. I'm very much not a fan of Go, but for lambdas it's 100% the choice I'd go with since anything else that hits all of thee pros Go has doesn't have anywhere near the same market share. Which now that I think of it is kind of just Go in a nutshell. The one pro of Go in lambdas versus Go on a server is that since lambdas are relatively small you don't run into some of the annoyances of scaling Go codebases.

I suppose I could just switch from GraalVM to a traditional JVM at that point, but what if I'm really relying on the small memory footprint, small binary size, or fast startup?

I've been programming in Go for 2 years now, and the book 100 Go mistakes and how to avoid them describes it quite fittingly from my perspective: "simple to learn but hard to master". The language constructs can be learned very easily, but learning to write solid idiomatic Go is pretty hard.On first sight the pull requests from juniors and seniors appear similar, but at my job, in a team of around 30 developers with varying experience, it is also easy to identify who has more Go experience.

I see your points about type system and other choices Go made but in general I’d say Go has even greater velocity than JS/TS. My justifications are as follows: - You don’t need to worry about the tooling around your dev environment, such as prettier, test runner, package manager, etc. because all of them come with the language. - The language itself is really small and one can learn all of it in one day. It’s even possible to read the whole specification doing that. - If you use something like htmx, then you can even get away with not touching any JS. - The one way of doing things is especially important when you want to read an open source project’s code. Also, the community mostly shares the simplicity mentality, so projects are mostly higher quality and easy to pick up. So, in my mind, the Go streches to the end of the velocity spectrum and they are exploring if they can also stretch to the perf end of it. The hesitation is mostly around not messing the dev velocity/ simplicity part.

For web apps, I would recommend building some boilerplate and keeping it as a repo that you can pull whenever you want to start a new app. The biggest plus point is how simple it is to set up a Go project, there is no complexity behind the scenes and things can be managed with ease because you control almost everything about your application.

I think you hit the nail on the head with "Writing Go doesn't make me feel clever." This is IMO why so few people contribute to Go projects, there is nothing to learn. Go is the perfect language to just get shit done. Its the Toyota Corolla of programming languages. Sure, some people turbo and race their Corollas, but most people just go from A to B and couldn't care less. PS: This is why I like Go so much. C++ and JS show the personality of the lead programmer in the codebase, no 2 codebases look the same.

Coming from an enterprise space, trust me, we *don't* want "clever" people. We want predictable results built in a predictable manner to deliver in a predictable timeframe. Go fills nicely that very important role. And yes, I 've been just checking out a bit Rust, and yes, toying around with it just a bit always made me feel "turbo hacker". But you know what? Most companies and most services and most situations don't need - or even worse - don't want turbo hackers. They want engineers who build proper stuff in a proper manner.

One great concept GO has implemented is errors as values, yes, they are annoying, but one day I decided to implement the concept in al my TS code with a simple helper return type that forced me to handle the error first before the actual return values were considered completely defined types, and from that moment I *never* had anything crash on me. I don't even need so many tests now because the control flow is so much better. When you throw and catch errors, you actually have no idea where the error will be caught and how it will be handled, which in itself could cause subsequent errors and crashes.

I do that too in JavaScript, I return an array, one value of which is an error (oftentimes just a boolean whethere there is an erro). And below the call is Just handle it like in Go. I still have try catch inside that thing that I call, but it's better this way, and in React/Nextjs which re-renders, you instantly have access to the error and not on the next render. Because with only try catch you need to set some error state inside the catch and that is only available on the next render, but what if it's a checkout button and you don't want your user to go further if there's error. It makes it easier to handle.

I haven't done much Go, but I use TS and Rust regularly and _strongly_ disagree with the developer velocity thing, not because it's subjective but because we often forget what it takes to make software other than "just writing code". Correctness, edge cases and error handling, maintenance and even just "reading the docs" are all things we software engineers have to do a lot of, and all of them are easier in Rust. Can I write a bit of software faster in Typescript than Rust, sure, if I don't care about bugs and weird behaviour, telling people what I've done or whether this will still work in a few months time.

I think that's the general mindset of theo/startups: get an mvp out the door, worry about safety later. However when not in a startup I'd say that Rust is overall faster than TS, considering everything that goes in sw dev. I wrote a bankend for a new project in Node, and sure it was "available" faster, but then a lot of my time went into debugging and catching errors and transpiling and managing dependencies and so on. So I decided to rewrite it in Rust, and the initial version took more time, but it worked without errors (except some minor logic errors).

@@araozu ​ Definitely agree, that's what I've seen working at a lot of "start ups" but it _can_ also be very short sighted. The two most egregious examples I've seen in my career: - Code that's broken, but no one realised it was broken because when you use `as` in TypeScript it doesn't actually convert from one type to another, which is what everyone seems to think it does (please never use "as" and also, dear TypeScript devs, please change Json.parse() to return "unknown" instead of "any") - Teams ballooning under the stress of trying to add new features while dealing with the interest payments on mountains of technical debt. This is still a problem in Rust, but much much less exaggerated than TypeScript It really doesn't cost as much as people think to do things... maybe not "right", but "better" the first time and you save yourself so much time later. As an aside on short-sightedness in start ups, I recently interviewed at a company who took pride in not writing tests because they wanted to go fast, but also talked about how developers were frustrated at having out of hours incidents and I literally couldn't believe the person interviewing me couldn't put those statements together. `as` is definitely the example I was going to use in my OP. Using "as" makes type casting seem trivial, but it doesn't actually check that you're right and in the best case, you get errors at runtime (but probably not where you did the "as" but where-ever you tried to use the data), and in the worst case, its just right enough that you don't get any errors, your code simply does the wrong thing and you may not use it. To do it correctly in TypeScript you need a type predicate which can be huge and easy to mess up and then you still need to generate an error when you use it. The Rust equivalent in a library like Serde is `from_str(data)?`

@@araozu keep in mind that you already solved most issues during your first version (in TS) and then rewritten it to Rust. You probably would be even slower starting from scratch in Rust just because you would have to think about more things, not just porting existing logic where you already solved things. And on the topic of "being faster working with a language" is not really a language thing, but your familiarity with it. If I write TS for 3 years and switch to Rust for a month, I'm quite sure I won't be faster in Rust because I have all this TS experience under my belt. Developer experience and velocity is a subjective thing really, but objectively yeah Rust does solve some things better depending on your use case.

I've been developing in Go for a bunch of years now - 6? 7? Anyway, I love it. I came from Assembler, then C, C++, Python and now Go. I've started to learn Rust, but I learned Go to a usable level in an hour, whereas Rust is like walking with rocks in your shoes - you can do it, but it's painful every step of the way. I'm excited by rusts possibilities, and I love the correctness and efficiency of it, but it has a super steep learning curve. As for the difficulties of writing serious projects in Rust, I've seen a number of devs, famously Prime, who discuss programming challenges that are trivial in Go but become trait monstrosities when it comes to Rust, particularly around databases and shared data. Since you haven't done much go, why not actually spend a week and try to write something useful and productive. I'm sure you'll surprise yourself with how easy it is, and how fast you can go.

Go’s dev velocity is by far better than Typescript’s when you are trying to build a production grade tool with robust fault tolerance and synchronization. You might go faster in typescript, but are you confident you are handling every error graciously? Are you sure if you need to change a library or two it’s not going to take weeks? Are you sure that the new developers can read through your codebase and understand in an efficient manor. This is where I feel Go has the edge. Also it’s quite amazing to not think about asynchronous code at all. No function coloring is one the of best things about Golang. Sometimes making a function async in Typescript propagates all over the codebase requiring major refactoring.

What Bodner clarifies is that other languages also use pointers, they just hide them from the user. Consider this Python code: class MyThing: def __init__(self, name): self.name = name def rename(thing): thing.name = 'a totally different thing' def main(): thing = MyThing('steve') print(thing.name) rename(thing) print(thing.name) main() python3 main.py steve a totally different thing In Go, the syntax of pointers make mutability explicit. By default, function arguments are immutable copies: package main import "fmt" type MyThing struct { name string } func rename(thing MyThing) { thing.name = "a totally different thing" } func main() { myThing := MyThing{name: "steve"} fmt.Println(myThing.name) rename(myThing) fmt.Println(myThing.name) } go run main.go steve steve The explicit syntax, I realized, has my best interests in mind! The design clicked, the mystery around the asterisk went away. Anways, I am still very junior, and will likely run into some quirks. But for now, I'm enjoying Go.

Rust compile times - are sloth-slow only if you're compiling for the first time, often every time fresh, inside a Docker container. Instead, if you're repeatedly compiling on a development machine during normal development, incremental compilation times are pretty fast. Not Go fast, but pretty quick. As for time-to-market, yeah Rust has quite a bit more friction than Go, and even slightly more than C++ I'd argue.

As for C++ vs. Rust, I'd argue that developer velocity / friction with C++ varies a lot with boundary conditions. If your project uses a package manager and employs decent tooling (static analysis, sanitizers) to mitigate most common footguns, and you have a small and decently experienced team, I agree that C++ will be more nimble than Rust. If you manage dependencies with CMake or some "bespoke" build environment, without state of the art tools and have a more heterogeneous team in terms of experience, I would bet that you get things out the door significantly slower than in Rust.

Depends on the interpreter. For example PyPy is much faster than CPython. Also, there are projects such as Numba which actually compile Python into native machine code, so you are still writing Python even if it's technically another tool written in C++ that's making it fast. The argument that "X language is not fast because really it's just C/C++ under the hood" does not make sense. You could argue in the same fashion that C or C++ are not really fast languages, acskhually it's the machine code generated by the compiler that's fast. When comparing Python vs. JS/TS performance you have to take all of these factors into account. Which Python interpreter are you using? Which JIT, if any are you using? Which JS runtime are you using? Just making blanket statements that one language is faster than the other one is not useful for much of anything.

Yeah, the investment benefit of writing Rust takes quite some time to pay off. This comes at a severe hit to iteration time. I would prefer 90-95% performance of C in Go with fast feature addition and good contribution in open-source than 98-99% performance of C with Rust. Majority of the projects just don't require that last bit of performance pinching. And the reward ratio for that last bit of performance is terrible and rarely required. For example, Rust in Linux kernel, good choice (let's ignore Zig for now). Rust in Cloudflare's Pingora framework, great choice. But rust in package managers, linters, build systems make no sense. The advantage from going from Go performance to Rust performance is not noticeable for 98% of the times. This also comes a cost of less features since iteration is slower in rust. Rust craze is extremely misguided and might harm Rust in the long term. Rust is not cut out to be a general purpose programming language even with better build times. Rust is in a unique niche of safety guaranteed systems programming language. Making it more than it is and advertising "Machine learning in Rust" or "Rust for data science" is stupid. All those have a good enough ecosystem figured out and switching to Rust is just waste of effort in every sense.

This is a good take. I listened to a presentation on Zig - and for one-shot CLI command's, memory safety isn't necessary at all. In fact, you can purposefully leak memory and just let the operating system clean it up once you are done. So if you want maximum possible speed, but a better developer experience than C or C++ then Zig would potentially be a better choice than Rust. But I'm also really interested in Go too. Maybe Go is an easier transition for Javascript devs if they want to help contribute - although this hasn't been the case as you pointed out for esbuild.

Language for writing compilers is another problem. Go does not really have anything specific to support building the compiler, I remember needing to have interfaces with one empty method to mark structs as AST nodes which just felt so wrong. Rust on the other hand initially seems really attractive with ADTs. Later down the line you might get stuck with Rust, for example if you want to represent recursive types in your compiler in Rust you will have to implement some kind of handle system as references are not really an option. That gets a bit annoying, in Go you could just hold a pointer. When choosing the language to write compiler in I think people tend to focus on the start or end of the process (parsing, simple analysis, vm) in which case Rust is really attractive but forget about data representation for typechecking and so on. But as compilers prefer immutable data structures and visitors/folders to operate on code I wonder how much that is actually a problem. I can tell from my experience of writing compiler in Rust that it slows down my development time initially as I need to think about central database that holds all the types so that they can be queried later. But maybe i would need to do this thing with Go anyway later and Rust just shifted it left?

I was hovering between liking and disliking this video and ultimately went with liking it. I don't necessarily agree that working in JS/TS will make you faster and "Dev Velocity" as a metric is very subjective. It can feel fast using JS array operations to break down data quickly. For example array.map().filter() feels like a more elegant solution and is much faster to write than writing for loops, but when you're debugging issues it's much easier to do that with for loops than functional operations. Yes JS/TS has a richer third-party ecosystem, but how much time are you spending having to audit and upgrade your various packages? This is less of a problem with Go due to its rich standard library meaning a lot of these packages are less necessary (and less tempting to automatically reach for when you need to left pad). I do think this is a good breakdown of the tradeoffs between these different languages, and well worth a watch though. One of the reasons I stay subscribed is it's nice to get a perspective from someone I often disagree with but still has valuable insights. Keep up the good work :)

Definitely the Typescript -> Zig pipeline is real, especially with Bun existing and clueing people into the existence of zig. All the fancy type magic you can do in Typescript is kinda actually possible (it IS all doable, just don't get any IDE help) Great thing about zig vs. typescript is the sudden relief from worrying if your code will port to a platform (consoles? Sure. Embedded? No problem!). As well as the feeling that your code once written is probably fast and light enough to use anywhere. Also the auto formatter is awesome - Just try adding a comma to the end of any initializer and watch the magic!

This video will help me decide what to do after I am done with what I wanted to learn from C++. If the thing I am making is super rigid sure I will pick Rust or C++, if the thing demands constant iterations safe bet would be TS/JS but if this thing is amphibious like we will have iterations but not as much as a JS framework and not as rigid as some OS firmware in this term Go becomes a lucrative option.

I agree! Elixir is a little different because it's far less "general purpose" than these languages. You'd probably want that 2D axis Theo mentioned. That said I'd love if he covered it since he always speaks so highly of the language

TS's "developer velocity" means you get to screw up way faster in production than other languages....... also, this "Rust is slow because of the borrow checker" is just... not true????? I get it, a steeper learning curve, but I wouldn't say it's THAT much steeper than, say, ES5 JS.

I don't see that gap in velocity between TS and Go, even in smaller projects. The amount of time I'm regularly spending dealing with issues around configs in a decently large TS codebase is ridiculous. Always slowed down by things not working properly in an increasingly fragile infrastructure.

Agree, dealing with all the packages and updating them and all the config files adds up. And all the extra tooling one needs to have, that too.

I'm a jobless beginner who just spend the last year learning standard full stack web development and AWS. Since the job market is so awful I'm looking to specialize and I've been heavily considering making the transition to Go. I think the simplicity would appeal to me, and I think I'm better at backend than frontend anyway.

All backend jobs around here are in Java. There are literally no Go jobs. So, be careful what you learn. If you want a backend job, go through Kunal Kushwaha course on youtube and you will have a backend job in a year or two. I don't know Java and I program Go btw, but that would be my recommendation.

I really like this video, but I think dev velocity is a lot more subjective than you lead on here. I feel like every time I spin up a TS project I have to faff around with configs and dependencies for far too long before even starting the project. I can move much faster with Go because of how much is built into the core. It really depends on what you are most comfortable/experienced with

I didn't think I'd love it and there are a fair few very strange decisions made in the language design (no immutability? that weird loop variable footgun which has been fixed now, small thing but gofmt not putting spaces in 1+1, etc.), but the concurrency is just so easy and fun. Building with Go feels like a breath of fresh air coming from TS as well. Everything is just so... simple, and fast! I always thought the whole if err == nil would bother me more as well but it sure beats exceptions. Copilot helps a lot with that stuff as well. It also is kinda nice to go back to writing just regular ol procedural code when everyone else is going in the functional direction. It feels cool at first to write arr.filter(...).flatMap(...).reduce(...) etc. but it does hurt me deep down knowing how much memory I'm wasting

As a python dev for a couple of years now, ive said multiple time that if i need speed and higher performance in my very high lvl language i can always work out integrations with very low system lvls languages to build performance without slowing down dev speed ( libs in c or rust ). I 100% agree with the feel of Go living in the middle. However when looking to explore a language that can give me a consistent ecosystem when building a monolithic project with frontend and backend as an experiment i found myself gravitating towards Go because of that mid consistent behavior. That gentler approach in dev speed you get from Go allows for still having a product with enough performance in general without making a huge compromise of the dev experience and in that sense i can see it being a great tool for integrated applications that may need to live as monolithic services. So there may be a space in market products for Golang after all

wonder if we just restrict ourself to use a subset of rust and enforce immutable copy using functional programming maybe much of the complexity can be avoided by code style
