Facing problem in function passing array

1

function nextInLine(arr, item) {
// Your code here

return item; // Change this line
}

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

how do i write the code for nextInLine([], 1) which would return 1

2

function nextInLine(arr, item) {
// Your code here… below is how I did it

//push will add item variable at the end of the arr(array)

arr.push(item);
//shift will remove the first element of the array

return arr.shift(); // Change this line… I changed this line also
}

make sure to add relation to what you did to the lines of code below, there will be a variable (testArr) change that to (arr). I don’t know about your challenge how it’s displayed but that’s how mine is and that’s how i did. I hope you got the point. :slight_smile:
