My code is still a mess, but I’m learning
I taught myself Go (and programming in general) by learning by doing. I learned by making a lot of mistakes and after noticing them, doing the necessary research. My Go code is probably a big mess, but it’s so satisfying, after not touching some code for a while, to do a major rewrite and improve the code with everything I’ve learned since the last time.
Today, for example, I replaced a lot of
io.Pipe, so that my program needs to allocate less memory and may run faster. I also replaced buffers with
string.Builder where it made sense. And finally, I got to know a new package:
errgroup. It helps to catch errors when using functions with error returns in goroutines.
As for the code mess, I admit that I have trouble structuring and organizing code. I can write code that does what it should do, but I really need to improve when it comes to separating the different logical parts of the code. Since Go is not an object-oriented programming language, it doesn’t matter as much there, but I also notice it when I work with Java in my day job. I should probably read some books about it, but first I have to finish my AWS certification.
I’m (still) a junior developer according to my job title, so please excuse any shortcomings in my code, as I’m still learning (and growing) a lot!
