Script Efficiency
Terser and Optimization
We use logic similar to professional tools like 'Terser' to ensure your code remains functional while being as small as possible.
Debugging Minified Code
Never try to edit the minified file directly. Always keep your source code readable and re-minify after making changes.
Frequently Asked Questions

For 99.9% of code, minification is perfectly safe. Exceptions only occur with very specific usages of `eval()` or function name string matching.
