What is the working of timers in JavaScript?

Question

Rahul Roi · Answer

As we know, the timer is a control of JavaScript. But the timers are used to execute a piece of code at a set time or also to repeat the code in a given interval of time. It is done by using the functions setTimeout, setInterval, and clearInterval.

When the setTimeout(function, delay) function is used to start a timer that calls a particular function after the mentioned delay. And, the setInterval(function, delay) function is used to repeatedly execute the given function in the mentioned delay and only halts when canceled. While the clearInterval(id) function instructs the timer to stop. And while the timers are operated within a single thread, and thus events might queue up, waiting to be executed.
