Creating Maps

Initialization

Create a map with make or a literal:

// Using make
ages := make(map[string]int)

// Using a literal
ages := map[string]int{
    "Alice": 30,
    "Bob":   25,
}

The make function creates an empty map ready for use. A literal lets you provide initial values. Both create a usable map. Choose based on whether you have initial data.
