Frequently Asked Questions

    
Is my JavaScript code safe to paste here?
Yes. All processing is done locally in your browser. Your code is never sent to a server, stored, or logged anywhere.

    
Will minification break my JavaScript?
Our minifier only removes safe whitespace and comments — it doesn't rename variables or do aggressive tree-shaking. For that level of minification, use a build tool like Terser or esbuild.

    
Why remove console.log statements?
Console statements left in production code expose internal logic, slow performance, and fill browser consoles with debug noise. Removing them is a best practice.

    
What about source maps?
This tool doesn't generate source maps. For source map support in production workflows, use a proper build tool like webpack, Rollup, or esbuild.
