Javascript Strigify Push and Shift given me error

Question

I am new to javascript, please help me with this code, where did I get it wrong?

function magix2(arrangment, figures) {
    arrangment.push(figures);
    return arrangment.shift();
}

var bum = [26,27,28,29,30,31,32];

console.log("Before: " + JSON.stringify(arrangment));
console.log(magix2(bum, 33));
console.log("After: " + JSON.stringify(arrangment));

`arrangment` is a local variable to `magix2` function, it's not accessible outside of that function. You need to retrieve `bum` instead. — Teemu, Jun 23 '20 at 06:24

function magix2(arrangment, figures) {
  arrangment.push(figures);
  return arrangment.shift();
}

var bum = [26,27,28,29,30,31,32];

//console.log("Before: " + JSON.stringify(arrangment));

console.log(magix2(bum, 33));

//console.log("After: " + JSON.stringify(arrangment));

arrangment is the argument of function, you can't access that argument outside the function, that's I commented out these console lines.

arrangment is an argument of magix2 function you can not access it outside. Try accessing bum instead.

function magix2(arrangment, figures) {
    arrangment.push(figures);
    return arrangment.shift();
}

var bum = [26,27,28,29,30,31,32];

console.log("Before: " + JSON.stringify(bum));
console.log(magix2(bum, 33));
console.log("After: " + JSON.stringify(bum));

The correct way to perform your operation. Console Return 26, as it is first element, also 33 is added to list
