Rewrite to class
importanza: 5
The Clock class (see the sandbox) is written in functional style. Rewrite it in the “class” syntax.
P.S. The clock ticks in the console, open it to see.
class Clock {
constructor({ template }) {
this.template = template;
}
render() {
let date = new Date();
let hours = date.getHours();
if (hours < 10) hours = '0' + hours;
let mins = date.getMinutes();
if (mins < 10) mins = '0' + mins;
let secs = date.getSeconds();
if (secs < 10) secs = '0' + secs;
let output = this.template
.replace('h', hours)
.replace('m', mins)
.replace('s', secs);
console.log(output);
}
stop() {
clearInterval(this.timer);
}
start() {
this.render();
this.timer = setInterval(() => this.render(), 1000);
}
}
let clock = new Clock({template: 'h:m:s'});
clock.start();
