cf1111c1c11feddfaeb1bdef Iterate with JavaScript While Loops 1 https://scrimba.com/c/c8QbnCM 18220 iterate-with-javascript-while-loops

--description--

You can run the same code multiple times by using a loop.

The first type of loop we will learn is called a while loop because it runs while a specified condition is true and stops once that condition is no longer true.

var ourArray = [];
var i = 0;
while(i < 5) {
  ourArray.push(i);
  i++;
}

In the code example above, the while loop will execute 5 times and append the numbers 0 through 4 to ourArray.

Let's try getting a while loop to work by pushing values to an array.

--instructions--

Add the numbers 5 through 0 (inclusive) in descending order to myArray using a while loop.

--hints--

You should be using a while loop for this.

assert(code.match(/while/g));

myArray should equal [5,4,3,2,1,0].

assert.deepEqual(myArray, [5, 4, 3, 2, 1, 0]);

--seed--

--after-user-code--

if(typeof myArray !== "undefined"){(function(){return myArray;})();}

--seed-contents--

// Setup
var myArray = [];

// Only change code below this line

--solutions--

var myArray = [];
var i = 5;
while(i >= 0) {
  myArray.push(i);
  i--;
}
