Maps:
*Iterate a map with range
Iterate a map with range
suggest changeIteration order is not specified. Go randomizes the order of iteration on purpose so that code doesn’t incorrectly rely on specific order.
Iterate both keys and values
people := map[string]int{
"john": 30,
"jane": 29,
"mark": 11,
}
for key, value := range people {
fmt.Printf("key: %s, value: %d\n", key, value)
}key: john, value: 30
key: jane, value: 29
key: mark, value: 11
Iterate just keys
people := map[string]int{
"john": 30,
"jane": 29,
"mark": 11,
}
for key := range people {
fmt.Printf("key: %s\n", key)
}key: john
key: jane
key: mark
Iterate just values
people := map[string]int{
"john": 30,
"jane": 29,
"mark": 11,
}
for _, value := range people {
fmt.Printf("value: %d\n", value)
}value: 30
value: 29
value: 11
