Overview
range keyword is used to iterate over arrays, slices, maps and variadic function arguments. It returns two values. On the first position is the index/kyes, and the second position is the value.
- Note that only a first identifier is declared, that is the index and not the value, as the intuition would suggest. See examples below:
var a [5]int
for i, value := range a {
// i is the index
// value is the value
}
