Iterate Through an Array with For Loop

JavaScript
#1

Tell us what’s happening:

Help me on this, i cant get the answer correct

Your code so far

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

var total;

// Only change code below this line

for (var i = 0; i < myArr.length; i++) {

total += myArr[i];

}

// 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];
var total;
// Only change code below this line

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

Tell me your expected output

I want this

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 .

Hey tau, you should declare total = 0 and then execute, that should work
