JS Comment Cleaner is a streamlined utility designed to sanitize JavaScript files by identifying and removing various types of annotations. It utilizes an advanced regular expression engine that distinguishes between code comments and strings, ensuring that elements like URLs or templated text remain intact while single-line, multi-line, and JSDoc comments are stripped away based on user preferences.

Beyond simple text processing, the app includes several productivity-focused tools such as a one-click copy function, local file downloading, and a theme toggle for comfortable use in both high-light and low-light environments. By automating the removal of developer notes and documentation, it serves as a lightweight pre-processing step for code optimization and obfuscation.
