Unlimited arguments in a JavaScript function

Question

Can a JavaScript function take unlimited arguments? Something like this:

testArray(1, 2, 3, 4, 5...);

I am trying:

var arr          


        

Answer 1

Javascript ES5

function testArray(){
    for(index = 0; index < arguments.length; i++) {
        alert(arguments[index])
    }
}

Javascript ES6

const testArray = (...arg) => console.log(arg)
