Kifungo cha Kuanzisha Timer kwenye JavaScript

Katika masomo yaliyopita, timer yetu ilianza kazi mara tu ukurasa upakizwe. Hebu sasa tutengeneze kifungo, ambapo kubonyeza kwake kitaanzisha timer yetu:

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

Tuandike JavaScript inayofanana:

javascriptlet start = document.querySelector('#start');

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