How do you create and use constants in Go?
← All Golang questions
Re-explain
Constants are declared using the const keyword and cannot be changed after declaration:
const Pi = 3.14159
const MaxUsers = 100
// Grouped constants
const (
StatusOK = 200
StatusError = 500
StatusPending = 202
)
// iota for auto-incrementing constants
const (
Sunday = iota // 0
Monday // 1
Tuesday // 2
)
