In this article, we will learn how to use setTimeout() and clearTimeout() in JavaScript. setTimeout is a function that allows us to run the function only once after some time. By using the clearTimeout function, we can cancel the execution of the function. setTimeout() in JavaScript...
To start with, within the first block of JavaScript, two timers are initiated: a 10mssetTimeoutand a 10mssetInterval. Due to where and when the timer was started it actually fires before we actually complete the first block of code. Note, however, that it does not execute immediately (i...
Javascript setTimeout executes only once after the delay whereas setInterval keeps on calling the callback function after every delay milisecs. Both these methods returns an integer identifier that can be used to clear them before...
