Possible bug Diff Two Arrays

Tell us what’s happening:
The code written below runs in both the chrome console, and in VScode, but when I try to run in it in FCC, nothing happens. Is this a bug? or is the FCC editor just picky?

Your code so far

function diffArray(arr1, arr2) {
    for(let i=0;i<=arr2.length;i++)
    if(arr2[i] !== arr1[i]){
        return arr2[i]
  console.log(diffArray([1, 2, 3, 5], [1, 2, 3, 4, 5]));

Link to the challenge:

the run button doesn’t work when there are syntax errors in the code.
I believe you need to add a semi colon after the line for return.
Also I heard (by reading on the forum) that you may need braces around your if statement too.

btw. the logic looks like it needs some work too…

woops, thank you :expressionless:
