Frequently Asked Questions
Why minify JavaScript?
Minifying JavaScript reduces file size, improves load times, and helps optimize bandwidth usage. It's essential for production deployments and better user experience.
Is it safe to remove console logs?
Yes, console logs are typically used for debugging and should be removed in production. Our tool safely removes them while preserving code functionality.
How does name shortening work?
Variable and function names are shortened while maintaining scope and functionality. This reduces file size without affecting code behavior.
What about source maps?
While this tool doesn't generate source maps, you can use build tools like webpack or rollup for source map generation when minifying in your development workflow.
