Tell us what’s happening:

Your code so far


function nextInLine(arr, item) {
 // Only change code below this line
nextInLine([], 5);
return item;
nextInLine([], 1);
return item;
nextInLine([2], 1)
return[0];
nextInLine([5, 6, 7, 8, 9], 1)
return[0][0]; 
 
 
 
 
 // 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));

do not call the function inside itself like that, everything crashes if you do that

try to understand what are the function requirements

3

@ILM can you re-write the code yourself

4

no, I will not give you the solution

try understanding what’s the corresponding output for each input

5

I will appreciate you rewrite the code.

6

I will not give you the solution

what have you tried other than calling the function inside itself?
