-SetTimeOut , SetInterval

setTimeOut - it call to function and execute our codes after a few menutes.

Additionally setTimeOut accepts these values

                         How it works ?

setTimeOut(()=>{console.log("Hello khusi")}, 8000);

and result showed after 8 secound.

.
We can type the third value as so.

setTimeout((text)=>{console.log("Hello khusi"+ text)}, 8000, "program");

and it demonstrate

setInterval - it works during the time that we add.

Secondly, setInterval take this kind of properties.

                      How does it work ?

"use-strict";

let btn=document.getElementById('start');
let timeText=document.getElementById('time');
let stopbtn=document.getElementById('stop')

let timer=0;

let timeCount=setInterval(()=>{
    timeText.innerHTML=`${timer}`;
    timer++;

}, 1000);

btn.addEventListener('click',()=>{
    setInterval(()=>{
        timeText.innerHTML=`${timer}`;
        timer++;

    }, 1000);

});

stopbtn.addEventListener('click', ()=>{
    clearInterval(timeCount)
})

Firstly it started to count automatically

then we stop it with stop button by clicking
