Add Elements to the End of an Array Using concat Instead of push

Tell us what’s happening:

Can you help me.What is going wrong here?

Your code so far

function nonMutatingPush(original, newItem) {
  // Add your code below this line
 return original.concat;
  // Add your code above this line
var first = [1, 2, 3];
var second = [4, 5];
nonMutatingPush(first, second);

Link to the challenge:

concat is function, so needs parentheses() after concat and then in parentheses you need to add the newItem.
Hope it helps.

In the original code, you should have simply changed the word push by the word concat

Oh my god this was very simple thank youagain
