// Before rest parameters, "arguments" could be converted to a normal array using:
function f(a, b) {
let normalArray = Array.prototype.slice.call(arguments)
// -- or --
let normalArray = [].slice.call(arguments)
// -- or --
let normalArray = Array.from(arguments)
let first = normalArray.shift() // OK, gives the first argument
let first = arguments.shift() // ERROR (arguments is not a normal array)
}
// Now, you can easily gain access to a normal array using a rest parameter
function f(...args) {
let normalArray = args
let first = normalArray.shift() // OK, gives the first argument
