Question 1

What is JavaScript minification?

Accepted Answer

JavaScript minification is the process of reducing JS file size by removing whitespace characters and comments, and shortening variable names. It can significantly improve page loading speed.

Question 2

Is JS minification safe?

Accepted Answer

Safe. Minification only removes whitespace and comments, and renames local variables. It does not change code logic or functionality. It is recommended to keep a backup of the original file.

Question 3

What's the difference between JS minification and obfuscation?

Accepted Answer

Minification aims to reduce file size — reduced readability is a side effect. Obfuscation aims to prevent code reading and actively uses complex transformations. Minification typically does not affect code execution performance.
