Speeding Up Array Processing in Go with the Slices Package
Find out how the slices package can help you speed up the processing of common array operations.
Working with arrays is one of the most common tasks in software development, and many languages, such as Javascript and Python, have implemented functional programming techniques to simplify this task.
With the advent of generics, it was only a matter of time before Go had something similar. The slices package provides many useful functions for this precise purpose.
In this article, we will take a look at the slices package and see how it can help you improve and simplify array processing in Go.
The slices package
The slices package is available from Go 1.21 and contains several functions that can be used to process many common array operations.
Based on generics, it allows standard logic to be applied to many array types, from strings to int32. It can also work with structures by defining custom comparison functions.
We will see later in the article how the approach changes depending on the type of slice being worked with. From Sort to Max, from Compare to Delete, there is almost everything you could need to work with…
