Example
people := map[string]int{
"john": 30,
"jane": 29,
"mark": 11,
}
for key, _ := range people {
fmt.Println("Name:", key)
}
If you are just looking for the keys, since they are the first value, you can simply drop the underscore:
for key := range people {
fmt.Println("Name:", key)
}
Note that when iterating over a map with a range loop, the iteration order is not specified and is not guaranteed to be the same from one iteration to the next.
