Why it's good to obfuscate your JavaScript source code?
There are two good reasons. First, you will stop theft of your JavaScript sourcecode. And second, its size will shrink for around 70% which will significantlyimprove download time and execution speed in the web browser.
What is obfuscation anyway?
The obfuscation is a process of replacing long descriptive function and variablenames like Customer, Salary, FirstName... with short meaningless names liked, g, m.... Comments and unnecessary whitespace characters are also removed.The functionality of the JavaScript code remains the same while source code changesdramatically. Obfuscated code is impossible to reverse-engineer and extremely hardor impossible to understand. It is better to distribute obfuscated version of yourJavaScript code and to keep your original JavaScript source code for yourself.
