Advanced Go: Slices continued

Adding elements to a slice

It is common to append new elements to a slice, and so Go provides a built-in appendfunction.

func append(s []T, vs ...T) []T

The first parameter s of append is a slice of type T, and the rest are T values to append to the slice.

The resulting value of append is a slice containing all the elements of the original slice plus the provided values.

If the backing array of s is too small to fit all the given values a bigger array will be allocated. The returned slice will point to the newly allocated array.

Do like it, if you found it usefull.
