Why Won't My Code Iterate Through an Array with a For Loop?

JavaScript
1

I ran this code for the section “Iterate Through an Array with a For Loop”, but it keeps saying that total should be declared and initialized to 0, and not to set it to 20. I have done precisely both of those things, but it’s still giving me an error.

// Setup
var myArr = [ 2, 3, 4, 5, 6];

// Only change code below this line
var total = 0

for (var i = 0; i < myArr.length; i++) {
total += myArr[i];
}

missing a ; on var total = 0

The tests can be picky

No problem, thank you for the tip; I’m new here. I will adhere to it from now on.

Cheers,

I still don’t quite understand what that means; do I replace the 0 with an a? It returns undefined when I do that. I put in myArr, but it still doesn’t return all green. How would you write the line that’s messing the program up?

You are still missing a ; .

Oh my god, I thought you meant I was missing “a”, as in myArr or something like that. Sorry about that, and it runs with no problems.

Thank you very much for that! I was breaking my head for almost an hour on this

Don’t worry man. Happens to the best of us.

Although, I thought the FCC challenges highlight simple syntax errors for you. That’s what the red squiggly lines are.
