Answer 1

You're looking for .set which allows you to set the values of an array using an input array (or TypedArray), optionally starting at some offset on the destination array:

destination.set(source);
destination.set(source, offset);

Or, to set a limited amount of the input array:

destination.set(source.slice(limit), offset);

If you instead want to create a new TypedArray, you can simply use .slice:

source.slice();
