Frequently Asked Questions
Does this rename variables to shorten the code further, like Terser does?
No - it focuses on removing comments and whitespace rather than full variable-renaming compression, so behavior stays predictable and easy to debug if something looks off.
Is it safe to minify code with template literals or regex?
Yes, standard JS syntax including template literals and regular expressions is preserved correctly.
Should I minify before or after testing my code?
Always test your original readable code first - minify only right before deployment, and keep the source version in version control.
