Tell us what’s happening:

Your code so far


function nextInLine(arr, item) {
// Only change code below this line

return item;
// Only change code above this line


}

// Setup
var testArr = [1,2,3,4,5];

// Display code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6));
console.log("After: " + JSON.stringify(testArr));

hey @erikdaniel650,

the item is just a number that you have to add to end of the array, then you need to take the number from the start of the array and return it.

3

then why would you put return next to arr.shift() wouldnt that just return nothing cause it took it away

arr.shift() will be the first item of the array if you console.log it and this is what the function needs to return, shift also changes the original array too.

let arr = [1,2,3,4]
let first = arr.shift()
console.log(first) // 1
console.log(arr) // [2,3,4]
