setTimeout allows us to run a function once after the interval of time.

In short, the method will be invoked only once after a defined delay time.

Code sample.

setTimeout(function() {
}, 0);


setInterval allows us to run a function repeatedly, starting after the interval of time, then repeating continuously at that interval.

In short, the method will be invoked multiple times after a defined delay time.

setIntervel(() => {

//This will be keep excecuting the code

setImmediate(() => {
