Jasob 1.5.1

JavaScript is scripting programming language used in millions of web pages worldwide. Scripting languages are not compiled, so JavaScript source code has to be downloaded together with the web page in order to be run by the web browser. This has several drawbacks and the most important one is that JavaScript source code can be easily viewed by anyone. All it takes is to open the web page in the web browser and to choose option View Source. This means that anyone can steal your JavaScript code, modify it and reuse it for his own purposes.

With Jasob your JavaScript code will become impossible to understand thus preventing anyone to steal and modify it. Its size will typically shrink for around 70% which will significantly improve download time and execution speed in the web browser. How Jasob achieves this? Jasob reads files with JavaScript code and replaces descriptive variable and function names like Customer, Salary, FirstName... with meaningless names like d, g, m... It also removes comments and unnecessary whitespace cha racters (space, tab, carriage return, line feed). The functionality of the code remains the same while source code changes dramatically. This process is called obfuscation, and the tool is called obfuscator. Obfuscated code is impossible to reverse-engineer and extremely hard or impossible to understand. It is better to distribute obfuscated version of your JavaScript code and to keep your original JavaScript source code for yourself.
