Dead Code Eliminator is a learning-focused project designed to analyze JavaScript files and remove unused functions, including both traditional and arrow functions. The tool creates a cleaned JS file with only the code that is actually used, improving maintainability and potentially reducing load times.
Highlights
- - Performs static analysis on single JavaScript files to identify unused functions
- - Removes simple functions and arrow functions while preserving functionality
- - Outputs a new optimized JavaScript file with dead code eliminated
- - Inspired by Lucana (https://github.com/Lacuna-JDCE/Lacuna)
- - Easily extendable to handle multiple JS files and analyze HTML for used JS functions
Impact
- - Helps developers reduce unused code and improve code maintainability
- - Provides a learning platform for understanding static code analysis
- - Serves as a foundation for building more advanced JavaScript optimization tools
Technical Overview
- - Language: JavaScript
- - Functionality: Static code analysis and optimization for unused JS functions
- - Output: Optimized JS file with dead code removed
- - Source code available on GitHub: https://github.com/l33t-c0d3r-66/Dead-Code-Eliminator
