let start = document.querySelector('#start') //it is a button
let stop = document.querySelector('#stop') //it is a button
let show = document.querySelector('#show')



let output
start.addEventListener('click', () => {

    //Before creating a web worker, check whether the user's browser supports it:
    if (typeof Worker !== 'undefined') {

        //check web worker whether undefined or not
        if (typeof output === 'undefined') {
            output = new Worker('looping.js') //(looping.js) is another file that you can processing anything
        }

        output.onmessage = (event) => {
            show.innerHTML = event.data
