How Our JavaScript Comment Remover Works
Our JavaScript comment remover intelligently identifies and removes all types of JavaScript comments while preserving your actual code logic and structure.
What We Remove:
- Single-line Comments -
// This is a comment - Multi-line Comments -
/* This is a multi-line comment */ - Inline Comments - Comments at the end of code lines
- Development Comments - TODO, FIXME, HACK, and other development notes
- Debugging Comments - console.log statements and debugging notes
- Commented Code - Temporarily disabled JavaScript code
What We Preserve:
- JavaScript Code - All functions, variables, and logic remain intact
- JSDoc Comments - Option to preserve documentation comments
- License Headers - Option to preserve copyright and license information
- Special Comments - Comments starting with /*! (often used by minifiers)
- String Literals - Comments inside strings are preserved
- Regex Patterns - Forward slashes in regex are not mistaken for comments
Smart Detection
Our tool uses advanced parsing to distinguish between actual comments and comment-like patterns in strings and regular expressions, ensuring your code functionality remains unchanged.
