// hay dos formas de hacer: 1(variables css y .setProperty para modificar las propiedades);
                          y 2(usando vien `` y clipPath=`circle()`).
                          
1) 
//solo agregamos correcatamente objeto.style.clipPath = `circle(50px at $(x) $(y))`; siendo x,y //variables de la función que gracias a `` se podran incluir.

2)
//javascript
let img1 = document.querySelector(".img1");
const t = img1.getBoundingClientRect();
function moverCursor(e){
    let m = e.pageX - t.left  ;
    let n = e.pageY - t.top  ;
    img1.style.setProperty(`--x`,`${m}px`);
    img1.style.setProperty(`--y`,`${n}px`);
}
img1.addEventListener("mousemove", moverCursor);

//css
.box {
   width: 500px;
   height: 250px;
   border: 2px solid red;
   position: relative;
}

.img1 {
   width: 450px;
   height: 240px;
   background-color: purple;
   --x: 0px;
   --y: 0px;
   --r: 50px;
   clip-path: circle(var(--r) at var(--x) var(--y));
}
//html
    <div class="box">
	<div class="img1">Hello word, hola mundo<br>Hello word, hola mundo<br>Hello word, hola mundo</div>
    </div>

How to Get the Domain From A URL Using Javascript

var urlParts = url.replace('http://','').replace('https://','').split(/[/?#]/);
var domain = urlParts[0];

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
