How do I make a function with delay in time using JavaScript?

Answer 1

const doSomething = () => { // do something here };

const timeInMilliSeconds = 3000;

// call function "doSomething" once after 3000ms

window.setTimeout(() => doSomething(), timeInMilliSeconds);

// call function "doSomething" repeatedly every 3000ms

window.setInterval(() => doSomething(), timeInMilliSeconds);
