  • We all know minimising our JavaScript files prior to moving a site into a production environment is best practise. The main reason why we do it is because compressed JavaScript files allow sites run faster at a lower bandwidth cost and (to some extent) make the code harder to understand.

    But what if we wanted to have the ability to render a JavaScript file completely unintelligible to prying eyes? This is the very question I asked myself prior to deploying a site I worked on to a live environment.

    Even though standard JavaScript minimisers remove comments, white space and use shorter variable names, we can take things a step further.

    I found a great site that manages to render your code into complete jibberish. You can give it a go by going to: http://javascriptobfuscator.com/.

    NOTE: Just as JavaScript code can be easily minimised, it can just as easily be “beautified” by going to: http://jsbeautifier.org/. Nevertheless, using the link above is a better deterrent when compared to other minimisers in my opinion.
