Go Slices

This lesson is part of Go · All levels

Summary

This lesson explains slice, data structure that contains a set of elements with dynamic lengths that are favorites in Go. Slice can be made directly with []type or via make(), and can be grown using append(). Internally the slice is a pointer to the array, length (len), and capacity (cap), so that the change in the element affects the underlying array.

Key points

Slice made with []type{} or make([]tipe, panjang, kapasitas)
Append() adds elements and copies to the new array when full capacity
Len() and cap() each return the length and capacity of the slice
Slice is a reference type; changes in the element are visible on the same base array
