Iterating javascript with loops

JavaScript
#1

Tell us what’s happening:
Describe your issue in detail here.
hello everyone, I cannot get my codes to produce [ 5, 4,3,2,1,0]. how should i go about it? And if you have other resources on understanding javascript loops kindly share it

   **Your code so far**


// Setup
const myArray = [];

// Only change code below this line

var i = 0;
while(i < 5) {
 myArray.push(i);
1++;
}

console.log(myArray);

Why 1++?

Since you are not changing i, this will loop forever.

You have some of the pieces you need here.

Your loop needs to use the numbers from 0 to 5. Your loop needs to put numbers in an array in the right order. Let’s start with getting the loop to go through 0 to 5. How do you do that?

Thanks :+1:
I finally figured it out

**My code **

// Setup
const myArray = [];

// Only change code below this line

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

console.log(myArray);

That’s all :blush:

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

The last code you posted still has a couple of errors.
Did you still need help?

The first issue here

If i<=0 then the condition will never be true because 5 is never going to be less than 0.
You need to change your condition so the while statement is true.

For here,

you don’t want to decrement 1 but instead decrement i.
When you decrement i, that is how you get 5,4,3,2,1,0

Hope that makes sense!

Glad to help.
JavaScript takes some time to learn so it is completely normal to stumble on challenges
