Rest Parameters

Rest parameters (denoted by ...argumentName for the last argument) allow you to quickly accept multiple arguments in your function and get them as an array. This is demonstrated in the below example.

function iTakeItAll(first, second, ...allOthers) {
iTakeItAll('foo', 'bar'); // []
iTakeItAll('foo', 'bar', 'bas', 'qux'); // ['bas','qux']

Rest parameters can be used in any function be it function/()=>/class member.
