Length can be used to determine the length of arrays, collections (anything that implements ICollection or ICollection<T>) and strings.
For nil values, 0 will be returned. This makes handling nil values easier, if you only care for the length.

var strLen1 := length("abc"); // 3
var strLen2 := length(default(String)); // 0
var myArray : array of Integer;
var arrLen1 := length(myArray); // 0
myArray := [1, 2, 3]; 
var arrLen2 := length(myArray); // 3
