Iterate Through an Array with a For Loop)

Tell us what’s happening:
where is the problem I don’t know?

Your code so far


// 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 myTotal =0;
// Only change code below this line
for(var i = 0;i<= myArr.length; i++) {
myTotal+=myArr[i];
}

you missed a step
the instructions say:
Declare and initialize a variable total to 0

So you need to declare ‘total’ and initialize and then use it in the new for loop

What exactly i would do

4

so to ‘declare a variable’ use the var keyword. to ‘initialize it’ then set it equal to 0
there is an example of this in the code with the ourTotal variable
