List.len
List.len(s) -> int
Returns how many elements s currently holds. It reads the slice's length, which changes as you List.push and List.pop, and is the same value as the bare len(s). Use it to bound a loop, test for emptiness, or find the last index with List.len(s) - 1.
Parameters
sthe slice to measureExample

var enemies: []int = new []int
handler Report phase Update {

}
