setTimeout(), clearTimeout(), setInterval() and clearInterval() : Everything you need to know

Let us understand these methods in a similar order as given in the title.

1. setTimeout() method:

This method allows us to run a function (or execute a piece of code) once the given interval of time expires.

Here's the syntax:

let timeoutID = setTimeout(functionName, time in milliseconds, arguments(if any))        

timeoutID is the value returned by the setTimeout. Although, we can name it anything.

Let's see an example:

function greet(){
     console.log("Welcome to my blog")
  }

setTimeout(greet, 5000)        

Output: It will print "Welcome to my blog". But it will take 5 seconds (5000 milliseconds) to do so (after the code is being run).

Let's see another example with a function that has parameters:

function greet(name){
     console.log("Welcome to my blog " + name)
  }

setTimeout(greet, 5000, "Elon")
