Iterate with JavaScript For Loops: erroneous output

Tell us what’s happening:

  1. My code doesn’t give correct output.
  2. in the previous exercise (while loop), variable i was declared outside the loop, but this step was skipped in for loop exercise. Isn’t it necessary to declare variables outside the loop?

Your code so far

// Example
var ourArray = [];

for (var i = 0; i < 5; i++) {

// Setup
var myArray = [];

// Only change code below this line.
for (var j = 1; j < 5; j++) {

Link to the challenge:

  1. You want 1 through 5. Look at when your loop stops: you’re telling it to finish before it gets to 5.
  2. You are declaring the counter - var i = 0 and var j = 1 are in the definition for each. With while loops, only have the end condition goes in the brackets: it’s not possible to declare the start condition in the brackets so you have to put it before. You can do the same with a for loop but it looks weird and would be confusing and pointless:
    var i = 0;
    for ( ; i < 5; i++) {
