Splat Arguments To A Function
Often times you have a function that takes a certain set of arguments. Like the following adder
function:
var adder = function(a,b,c) {
return a + b + c;
};
But you are left trying to pass in arguments as an array (e.g. [1,2,3]
). You want to be able to splat the array of arguments so that it matches the function declaration. This can be done by using apply
.
> adder.apply(undefined, [1,2,3])
