Arguments in javascript

Something Like that:
Arguments

What is Arguments in javascript
The parameters you pass to a function
(Javascript gives you a keyword of the same name which contains them all)

For that you need to create first html code.

HTML

<p id="demo1"></p>
<p id="demo2"></p>
<p id="demo3"></p>
<p id="demo4"></p>
<p id="demo5"></p>
<p id="demo6"></p>
<p id="demo7"></p>

After that add this JS code.

JS

function greet(firstname, lastname, lang, ...other){ // ...other add extra value on parameters
    lang = lang || 'en';

    if(arguments.length === 0){
        document.getElementById("demo1").innerHTML = 'Missing parameters!';
        document.getElementById("demo2").innerHTML = '-------';
        return;
    }
    document.getElementById("demo2").innerHTML = firstname;
    document.getElementById("demo3").innerHTML = lastname;
    document.getElementById("demo4").innerHTML = lang;
    document.getElementById("demo5").innerHTML = arguments; 
    //default variable of Javascript
    document.getElementById("demo6").innerHTML = 'arg 0: ' + arguments[0];
    document.getElementById("demo7").innerHTML = '-------';
}
greet();
greet('John');
greet('John', 'Deo');
greet('John', 'Deo', 'es', '111', 'my');
