Exercise of javascript: Iterate Through an Array with a For Loop (what's wrong?)


Declare and initialize a variable total to 0. Use a for loop to add the value of each element of the myArr array to total.

// Example
var ourArr = [ 9, 10, 11, 12];
var ourTotal = 0;

for (var i = 0; i < ourArr.length; i++) {
ourTotal += ourArr[i];

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

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

for (var x=0; x < myArr.lenght; x++){
total += myArr[x];

for (var x=0; x < myArr.lenght; x++){

You may want to check the speling on that line. :wink:

Common mistake, we all do it at least once. I do it at least once a day.


Oh my god Thank you. I was stuck because of that *facepalm :joy:


It happens. Trust me, it won’t be the last time. One frustrating thing about JS is that it lets things like this slide and you have to hunt for them.
