If you are transitioning into Go from a language like Python or Ruby, at some point or another you are going to start missing one of the many helper functions offered by the language. The most recent example of this for me was when I wanted to shuffle a slice. In Ruby this is as simple as calling the shuffle method. array = [1, 2, 3, 4, 5] array.shuffle # shuffles the array!
In this post we discuss what causes some changes to slices to be persisted even when they are passed by value, why this ultimately happens, and how to avoid it.
Learn about the difference between capacity and length and how to properly utilize them to make your Go code faster, cleaner, and memory efficient.
