Button for starting a timer in JavaScript

In the previous lessons, our timer started its work as soon as the page loaded. Let's now make a button, by clicking on which our timer will start:

<button id="start">start</button>

Let's write the appropriate JavaScript:

let start = document.querySelector('#start'); start.addEventListener('click', function() { let i = 0; setInterval(function() { console.log(++i); }, 1000); });

Make a button, by clicking on which a countdown will be displayed in the console, starting from 100.
