re-pass REST params?

Question

Say I have two functions that expect ...rest parameters

private function a(...myParams):void
{
    trace(myParams.length); // returns 3 parameters 1,2,3
    b(myParams);
}
private function b(...myParams):void
{
    trace(myParams.length); // returns 1 parameter (array) [1,2,3]
}

a(1,2,3);

The function a gets an array of parameters 1,2,3 but when it passes them to function b, it passes them as 1 parameter (an array containing the 3). Is there a way to pass them as 3 separate parameters instead of an array?

Answer 1

Yes, use the apply method that all functions have (functions are objects too!). So, rather than this:

b(myParams);

You'll do this:

b.apply(this, myParams);
