FAQ
Does minification affect JavaScript functionality?
No, proper minification only removes unnecessary characters. Your code works exactly the same way.
What's the difference between minification and uglification?
Minification removes whitespace and comments. Uglification goes further by shortening variable names. Our tool performs basic minification.
Should I minify for development?
