Format your messy JavaScript (JS) source code to make it easier and faster to read and understand.

Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” — Martin Fowler

What is Beautifying?

Beautifying or formatting source code is to reformation of source code to improve code readability, based on an analysis of the syntax for a human for some user-defined conventions like re-indenting codes lines, splitting the code into lines, creating blocks, adding white spaces at required places to make it easier and faster to read and understand.

    Difference of Formatted JS and Minified or non Beautified JS

Non Formatted JS:

function loadData(parameter){$.get('https://www.google.com',function(data){console.log(data)
showData(data)});}
function showData(data){document.getElementById("set_data").innerHTML=data;}
window.onload=function(){console.log('page loaded')}
alert("Testing functionalities");

Beautified JS:

    function loadData(parameter){
        $.get('https://www.google.com', function(data) {
            console.log(data)
            showData(data)
        });
    }
    function showData (data) {
        // body... 
        document.getElementById("set_data").innerHTML = data;
    }
    window.onload = function(){
        console.log('page loaded')
