How Our JS Compressor Works
We use a set of optimized regular expressions to identify and remove redundant code segments. This includes:

- Whitespace Collapse: Minimizes spaces and tabs while preserving string literals.
- Line Break Optimization: Combines lines where possible to reduce the overall line count.
