Initialize multidimensional boolean array as all false Unity JS

When you initialize a multidimensional boolean array, is it possible to set them all to false, or would you have to loop through each value and assign to false?

Booleans are structs, which are always initialized to false anyway.

You need to create the array first. When the array is created, all booleans have false value, as that is the types default. You don't need to set each individual boolean value, but you need to create the array.
