Tell us what’s happening:
Describe your issue in detail here.
The instructions say to declare and initialize a variable total to 0. But doesn’t “initialize” mean to put it inside the for loop parenthesis as the initialization?
**Your code so far**
// Setup
const myArr = [2, 3, 4, 5, 6];
// Only change code below this line
let total = 0;
for (let i = 0; i < myArr.length; i++) {
total += myArr[i];
}

Challenge: Iterate Through an Array with a For Loop
“initialize” just means to give it a starting value when you declare it. It doesn’t have to ne in a for loop. In the code you have, myArr, total, and i are all initialized, just in different places.
To initialize it just means to give it an initial value. It needs to be initialized as it would be undefined otherwise and you can’t work with it. If you initialize it inside the for loop it would be initialized each time the loop runs.
If you’re talking about these paranthesis (let i = 0; i < myArr.length; i++)
then no. Nothing else gets initialized there other than the i which is your number of iterations that the for loop does.
