Creating with make

Allocating slices

Use make to create a slice with specified length:

nums := make([]int, 5)

This creates a slice of length $5$ , all zeros. You can also specify capacity:

nums := make([]int, 5, 10)

Length $5$ , capacity $10$ . The extra capacity allows growth without reallocation.
