Iterate with JavaScript While Loops

Iterate with JavaScript While Loops

While loops will run as long as the condition inside the ( ) is true. Example:

while(condition){
code...
}

Hint 1:

Use a iterator variable such as i in your condition

var i = 0;
while(i <= 4){
}

Spoiler Alert Solution Ahead!

Solution:

// Setup
var myArray = [];

// Only change code below this line.
var i = 0;
while (i <= 4){
    myArray.push(i);
    i++;
}
