With C++ you can just have a coffee break when it's compiling instead

@@F1nnyF6 Incorrect. C++ is very very fast in terms of compilation and caches everything. Rust is the one that's fucking slow as hell; probably the only thing I hate about Rust is compliation time, which is the worst out of every language in existence.

$ is not Bash spawned in Bun, it's its own minimal semi-compatible Bash-like language that deals with the core of stuff we normally do in CD, and you can pipe stuff hither and dither into JS buffers. But it's NOT Bash, just a lexar and interpreter back into the Bun JS runtime (so any bug-fixes or improvements to Bun also applies to this process), so any tools that works checking JS code can check this. It's really good for offloading a lot of multi-OS scripting into a simpler platform. I use it for a lot of infrastructure stuff, I hate Bash / Ash cross-platform nonsense with a passion.

[@keyboard_g]

The cross platform bash compat is so Windows devs can cut and paste from any tutorial online and expect it to work.

[@havocthehobbit]

people complain when devs dont give short concise updates instead of just throwing out mounds of documentation , then people complain when they do and point out ambiguity as if the info should have been a 1 hour video that few would have watched to beyond half way. The poor fellas appear to have tried and got out of there comfort zones , so I appreciate this even tho I probably wont adopt bun until new project just like I havnt adopted deno yet.

many of the bun speed gains come from implementing things natively and comparing with JS based packages so they may be actually doing exactly the same thing, just more efficiently

19:00 just because different languages compile to an intermediate language, doesn’t necessarily mean the resulting output is comparable in terms of performance. The resulting intermediate code will be different for each language and will be compiled into actual bytecode. And it’s obviously not guaranteed that that last step will always result in identical performing bytecode, given different inputs.

I will never diss on optimizations in software used by many devs. A lot of this may seem inconsequential, but if you've ever worked with a compiler like tcc you'd know how good it feels to compile and run a large project in < 50ms Entire problem sets disappear when you can just do the naive thing and have it be realtime

Compiling and running a large project in < 50ms is cool, but is it especially noteworthy that your 20 second build now finishes in 19.9 seconds?

[@javiasilis]

@14:18 I used to wait 182 seconds for my react project to cold start when I was using webpack (260K LOC) w/TypeScript. That and the fact that I had barrelled all the exports within Create-React-App because there was no path aliases made it a nightmare. I saw glory when I migrated it out to Vite. Cold Start - 28seconds. Cached, it would boot up in 4 - 5 seconds. It was important when you messed up with tsc and it had to restart to pickup the changes.

[@laztheripper]

Last version got me excited to try Bun, to migrate some of my stuff, but quickly found out it didn't run directly on Windows. So this release made me migrate my website to Bun. Unfortunately, I have to say I did not see an improvement in performance. It was ~20% slower than node running "vite build" and "vite dev". Long running functions ran ~20-30% slower. Startup was slightly faster, and so was install, but I really don't care about the performance of my site when it's not even handling requests yet. So I did a little search and found out it's just that JSC optimizes less (faster starts) but runs slightly slower afterwards compared to V8. That said, I still plan on keeping Bun around for package management and the handy one liner to create an .exe from your JS/TS code.

[@LeeKao]

The dev's might only do "Bun install" once, the CI/CD does it all the time, that 18X improvement will increase your actual velocity when working on large scale project with deployment pipelines.

It is just a shame, that such a video came out on April 1st. The only day of the year when people question if what they read on the Internet is true. Some of it sounds clearly like BS though, especially some of the Performance stuff. 9:33: (Who uses the same scripts on Mac, Win. and Linux?) That would be me. I'm forced to run Windows at work. I have to use MacOS for debugging PWAs on iPads. I Run Linux at home. Having the same helperscrips just work everywhere sounds amazing.

Windows is the best desktop OS, it's not perfect, but takes next to no effort to get it to be B+ while sure, you can master your Linux install to get it to an A+ but at what cost? that being said: if you have to develop directly on host RUN AWAY we have WSL and full fledged VM's for a reason also powershell is a better scripting language than bash, it saves you from so many string manipulations! but yeah, it's not great either, just slightly less broken

[@jancartman321]

Same. It's clearly the devs choice and not necessarily the language's fault. You can create a Go project with 100 deps or with just one (postgres driver, e.g. pgx). The same is true for Node. It has everything you need for the basic server except for the postgres driver (postgres.js has no additional deps). When Prime is talking about 100 deps for a web service, then it's not Node's fault but the fault of the sloppy devs who include every piece of crap from NPM. Rust is a different story, as the std lib is not as comprehensive as Go's or Node's. Listing all deps for a basic Axum and postgres backend is a bit disturbing.

9:42 Well you do work primarily at Netflix, so are going to be using primarily web-server technologies. Most web-servers are linux only.

The thing that makes me not be able to use bun as a node drop-in replacement is that they don't support node-gyp dependency building and they don't automatically insert their bun-specific dependency in imports. *specific actual example*, I have a wrapper around better-sqlite3 with 5+ million views. This wrapper cannot be used in bun because better-sqlite3 isn't buildable in bun, and I'd have to make a branch/more code/environment checker, to change the *import* I'm using in order for my module to be useable in bun. Just to save 30 nanoseconds to run tsc --help, I guess?

[@bluegreenbugs]

There is one things between language. They can be more expressive on type and memory access pattern that are reflected in the intermediate language. So even if all language end up using LLVM, they can have different performance outcome. A very excessive example in that regard would be to compare ISPC vs C++ both using LLVM. As ISPC express data parallelism, LLVM can generate SIMD code by default and so the code generated when using ISPC will be faster than a C++ code that just use C++. Same things happen with rust, as it express more information memory access and ownership, the generated IR has more information and LLVM can generate better binary at the end. My understanding is that zig is also better than C++ at expressing this memory ownership and data parallelism problem, so even with a LLVM backend, zig could be better than C++.

9:40 Letting devs choose which platform they prefer is not a bad thing. Many companies let you choose between mac or pc when you join and it means those devs will run into cross platform issues. I mean, this is less than ideal, but I think it is a great addition to be able to support both platforms at once. Also, you may have .NET developers make the jump into other technologies or just be temporarily assigned to another project. It would make no sense to order a 3.5k$ Mac for such a short amount of time. Linux computers are also very hard to manage at scale for enterprise companies with very rigorous security policies, hence the Windows computers. You may call skill issues here, but this is the reality and most of the IT workforce out there is mostly used to manage Windows computers with a mix of Mac. 🤷‍♂️
