Overview

Go only supports four types of constant

• Numeric ( int, int64, float, float64, complex128 etc)
• String
• Character or rune
• Boolean

Go doesn’t support const map. So below program would raise a compilation error

Example

package main

func main() {
	const e = map[string]int{
		"a": 1,
	}
}

Output

const initializer map[string]int literal is not a constant
