Introduction to Slices

Flexible collections

A slice is a flexible view into an underlying array. Unlike arrays, slices can grow and shrink. They're the go-to data structure for collections in Go.

Declare a slice without a size:

var numbers []int  // slice of int (no size)

This creates a nil slice with no underlying array yet. You'll learn multiple ways to create and populate slices in the coming units.
