`for-in` loops work with both builtin container types (arrays and maps).
They allow to iterate the keys/indices and values.
<syntaxhighlight lang="bait">
fun for_in_array() {
arr := ['1st', '2nd', '3rd']
// Iterate over array indices and elements
for i, val in arr {
println('${i}: ${val}')
}
// Using only one variable will iterate over the elements
for val in arr {
println(val)
}
// To only iterate over the indices, use `_` as the second variable name.
// `_` is a special variable that will ignore any assigned value
for i, _ in arr {
println(i)
}
}
fun for_in_map() {
nato_abc := map{
'a': 'Alpha'
'b': 'Bravo'
'c': 'Charlie'
'd': 'Delta'
}
// Iterate over map keys and values.
// Note that, unlike arrays, only the two-variable variant is allowed
for key, val in nato_abc {
println('${key}: ${val}')
}
}
fun main() {
for_in_array()
println('')
for_in_map()
}
