Iterate Through an Array with a For LoopPassed

JavaScript
1

Tell us what’s happening:
I wrote a code following the instruction. It has not been accepted. I have reviewed others posts, but the only difference I have seen is i instead of total. I understood that I can declare any variable and the same variable I can initialize to run a code.

Your code so far


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

// Only change code below this line

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

You can’t use total as both the index variable and the sum.

Well you can, won’t cause a syntax error, but the results won’t be what you want.

My another mistake was that I wanted to add the next number and assign to “total” variable as well as to check the length of the array. This will throw undefined. Thank you both
