JS Minify

What is minification in JavaScript?

Minification, also known as minification, is the process of removing all unnecessary characters from JavaScript source code without changing its functionality. This includes removing whitespace characters, comments, and semicolons , and use shorter variable names and functions. Minification of JavaScript code results in compact file sizes.

Minification speeds up web page loading, thereby improving the website experience and satisfying both visitors and search engines.

What is the difference between minification and obfuscation, compression, encryption or uglification?

• Uglify: This is basically the same as minification. UglifyJS is a JavaScript library for minifying JavaScript files. To "uglify" a JavaScript file is to use Uglify to minify it. Ugly improves performance but reduces readability.
• Encryption: This is the process of converting data (called plain data) into encoded data. This encrypted or encoded data is called ciphertext and requires a secret key to decrypt it. Browser Unable to execute encryption code. Encryption is a security feature and does not necessarily reduce file size.
• Obfuscation: This process is used to hide business logic. The code is modified so that it cannot be read by humans, which makes reverse engineering difficult. The difference between obfuscation and encryption is that computers can still understand and execute the code. Obfuscation is achieved by changing the names of variables, functions, and members. File size reduction also improves performance, although this is not the primary goal of obfuscation.
• Compression: Data compression is the process of reducing the number of bits required to represent data. Data compression frees up valuable space on your hard drive, speeds file transfers, and reduces network bandwidth costs. Some Archives (such as Microsoft Word archives) may be compressed to 90% of their original size.
