"while loop developer" how to use pug/jade, scss, javascript, python(backend) - (Stack Tutorial 2)

Hi guyes,
This is tutorial 2,
The previous tutorial we have learnt how to use for loop pug/jade, scss, javascript, python(backend) Here you can see
This tutorial we will use basic while loop in our stack web development.

1. PUG/JADE
In this pug/jade tutorial we can use this pug to html converter for practice purpose PUG TO HTML

Example 1

- var i=0
ul
 while i < 10
  li= i++

2. SCSS

Example 1

$border: 1;
@while $border < 10+1{
    li:nth-child(#{$border}){
        border: #{$border}px solid red;

    }
    $border: $border+1
}

3. Javascript
while loop
Example 1

let li = document.querySelectorAll('li');
let i = 0;
while(i < li.length){
    li[i].style.color = 'yellow';
    console.log(i)
    i++;
}

while loop with do (js)
Example 2

do{
    li[i].style.color = 'yellow';
    console.log(i)
    i++;
}
while(i < li.length)

"do" and while is very simple to use and the "while" making the condition and the "do" execute the callback.

Finally, Python
4. Python

Example 1

count = 0
while count < 10:
    print(count)
    count+=1

It almost looks little same as javascript but python has only 2 primitive loop
