Question

For example suppose I have the following two functions

function a(param1) {
    console.log(param1);
}

function b(func, params) {
    func(params);
}

then

b(a, 1);

prints ‘1’ as expected

Now suppose I have an additional function

function c(param1, param2) {
    console.log(param1, param2);
}

Is there some way of doing something similar to

b(a, 1);

Except feeding in two parameters? Something like the following

b(c, [2, 3]);

Where the [2, 3] arrray is unrolled into individual parameters

Answer 1

Something like this:

function b(func) {
    func.apply(null, [].slice.call(arguments, 1));
}
