What is Javascript obfuscation?

Obfuscation is the process of turning JavaScript code into a format that is extremely difficult for a  human to read/understand (human unreadable code). This function is performed by compressing (minifying) the original code. The purpose of obfuscation is to protect the code and make it difficult to reproduce or reverse engineer.

Obfuscation makes use of  ASCII codes to simply replace characters with letters, use non-defined names to change variable names, or overcode.

When you obfuscate a javascript code, you are protecting it from being stolen or copied. Obfuscated code is more difficult to read, making it intentionally less likely that someone will be able to read, understand or modify it. You are also increasing the performance of the code, as the obfuscator eliminates unnecessary characters and shortens code length. You can try our Javascript Obfusctator
