Functions in JavaScript (js)

To create function in javascript we should write just:

function hello() {

For example lets call Alert with text Hello World :

function hello() {
alert("Hello World");

And call this function:


If you need to send some parameters in function, just write like this:

function hello(s) {
hello("Hello World");

We call this function with parameters and you can see “Hello World” in alert again.
