Go (Golang) Tutorial #4 - Printing & Formatting Strings

[@abgvedr]

Wonderful. A C++ dev over here of 8 years, started learning Go, and the more i learn the more i love it. Thanks for tutorial!

[@nitin0001]

Thanks for starting this series, I have been waiting for this

[@MarcusBryan1990]

Your channel is the reason I now own a house.

[@NetNinja]

Haha, thanks Marcus! :)

[@prophetjamz94]

I needed this series

[@MaxProgramming]

Thank you so much Shaun! Will you also make a series on REST API in Go? Edit: Did you notice how quick VS Code showed the errors while working with Go compared to JS

[@NetNinja]

Hey, yeah I will be doing more on Go in the future - probably a series on testing & one on creating an API :)

[@MaxProgramming]

@@NetNinja Thank youuu 🤩

[@noaexel]

@@NetNinja what is the recommended framework for development in Golang,

[@TahirBhai]

@@noaexel yeah also looking for the reply

[@void_star_void]

what about string interpolation like in js ? ` some string ${someVar} `

[@0xPanda1]

thank you Shaun

[@void_star_void]

Keep'em comin mate 😍

[@noaexel]

Thank you for this shaun, however i have 2 questions, 1. I noticed you don't end your statements with a semicolon, is it not required? 2. I also noticed that when you run your main file to demo your examples, its takes some time to output on the console, why is that? Thank you...

[@TahirBhai]

Yeah I noticed it too, thnx for comment

[@shr1han]

1. It's kind of like Python. If you've used it, you should know that there's no semicolons. But, if you write multiple statements in a single line, you need to write first statement, semicolon, then another... 2. It takes time because it needs to compile everything and then run the program.

[@sreekar_s]

Does vscode provide intellisense?

[@MaxProgramming]

Installing the Go extension for that is useful

[@LoveisHell85]

Great series. I would love to see React/Node/PostgresSQL fullstack project in the future. Thank you

[@gyenabubakar]

You mentioned that you'll leave a link to the format specifiers but I'm not seeing it in the description.

[@laragram]

Here: golang.org/pkg/fmt/

[@nanaarhin5567]

How are you able to switch between the terminal and the console. I am new to this program and the software as well and I it makes the learning a bit slow if I have to keep clicking between the terminal and where I am writing my code. Please help

[@themannyzaur]

learn your editor and its shortcuts for faster productivity in this case it's Ctrl + ` ` is found above the Tab key

@The Net Ninja,Can you please consider uploading full series of styled components for React

[@SiddharthRay1]

thanks Shaun!

[@dlysele]

In the formated string, when I did fmt.Printf("my age is %v and my name is %v", age, name), at the terminal, there would be a % at the end of the sentence, do you know what that is?

[@sreenirnair]

That is actually the command prompt for the next line. When you use Printf, unless you terminate the string with a character, the print stops in the middle of the line and the command prompt shows up in the middle of the line as % (if you are using zsh). To avoid this, add a , like fmt.Printf("My age is %v ", age) etc. PS: Println automatically adds a new line, but Printf behaves differently.

Thank you Mr.Pelling!

[@apoorvsinha4136]

I was looking at a Indian tutorial by Hitesh which has millions of views but turns out bigger number of views doesn't always mean better information. Switching to this series.

[@NetNinja]

Awesome, hope it's helpful :)

[@oglothenerd]

You should have explained why %q was changing the number to a character. (Essentially, 35 is the ASCII code for '#'.)

[@breawen]

yeah, at first i though it outputs '#' because it was an int. glad i tried it with a different number, making me realize what it actually does.

[@oglothenerd]

@@breawen :D

[@ch0wderz912]

What jobs requires Golang?? lol I need a job so I don't look like a dissapointment, anyways coding is fun! Is Golang a necessary language for Cybersecurity??

[@manh9105]

Go seems to have been heavily inspired by C

[@ginnerzapata5909]

it was made by the creator of B (the predecessor of C)

[@splytrz]

when a language doesn't have string inerpolation in 2023... :/

[@sahilchanglani8886]

what's the difference between using sprintf to assign a variable and assigning string directly to the variable?

[@krzysztofrapior8597]

Most likely it's just a design. Compiler (if it's smart) should do the same job in the end.
