How to create an accurate timer in JavaScript?
To create an accurate timer in JavaScript, we should get the time from the Date object.
For instance, we write
setInterval(() => {
console.log(new Date().toUTCString());
}, 1000);
to call setInterval with a callback that gets the latest datetime with the Date constructor.
And we call toUTCString to return a human readable datetime string.
1000 is the 2nd argument so the callback runs about every 1000 milliseconds.
Conclusion
