--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--;
}
