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.

function loadData(parameter){$.get('',function(data){console.log(data)
