Meet Javascript Beautifier, a simple online tool that does exactly what it says; beautify JS quickly and easily. Prettify your JS in a hassle-free way, or beautify it into human-readable format.

How does JS Beautify Work?

A minified JS source code may be reversed using a beautify (or prettify) process, which applies various stylistic formatting conventions to it. Js beautify formatting conventions usually adjust positioning, spacing, and similar modifications intended to make the content easier for people to view, read, and understand.

How beautify JS is different than minify JS?

Minify (or uglify), in computer science, is the process of removing all unnecessary characters from source code without changing its functionality. These unnecessary characters usually include white space characters, new line characters, comments, and sometimes block delimiters, which are used to add readability to the code but are not required for it to execute. Minified source code is especially useful for interpreted languages deployed and transmitted on the internet (such as JavaScripts) because it reduces the amount of data that needs to be transferred.

Why you should prefer JS and use Javascript formatter?

JavaScript (JS), along with HTML and CSS, is one of the core technologies of the World Wide Web (WWW). Every browser natively supports the three. For many, techies and non-techies alike, JS has long been associated with front-end development; that 'thing' you needed to add a bit of extra stuff on a webpage. In the last decade, JS has gained pace as an 'everything' language.

Windows, the king of native Windows-only apps, even made a whole editor in JS and published native Windows React bindings so it's possible to build native Windows apps in JS. Then there are Google's serverless functions, which only execute node.js. JS is even an option for overcoming the massive hurdle of interoperability in IoT.

Here's a telling statistic: more companies use JS on their back-end than either Python or Java. JS also has the most open source projects on GitHub. And alongside more widespread use, JS is being used for increasingly complex scenarios. NASA even trust it for managing essential spacesuit data in space. For NASA, the ability to build a simple, end-to-end application with centrally located data at a small cost was what drew them to JS. If that's not a first-class use, then what is?
