A collection of sweet.js macros that implement ES6 syntactic features for ES5 JavaScript environments.
es6-macros is a collection of sweet.js macros that implement ES6 syntactic features for ES5 JavaScript environments. It allows developers to write code using modern ES6 syntax like destructuring, classes, and arrow functions, then compiles it to ES5-compatible JavaScript that runs everywhere. This bridges the gap between modern JavaScript development and production environments that lack full ES6 support.
JavaScript developers working in environments limited to ES5 compatibility who want to use modern ES6 syntax features. This includes teams maintaining legacy codebases or targeting older browsers and runtimes.
Developers choose es6-macros because it provides a lightweight, compile-time approach to using ES6 features without runtime overhead or polyfills. Unlike transpilers that transform entire codebases, it offers selective syntax enhancement through sweet.js macros, giving developers fine-grained control over which ES6 features to adopt.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows incremental use of specific ES6 features like destructuring and arrow functions without a full transpiler, enabling cleaner code in legacy ES5 projects as highlighted in the README's modular approach.
Generates source maps during compilation with the -c flag, improving debugging by tracing ES5 output back to original ES6 syntax, as documented in the usage examples.
Uses sweet.js macros for compile-time transformations, avoiding runtime polyfill overhead and keeping the output efficient, aligning with the project's pragmatic philosophy.
Provides a clear view of how ES6 syntax compiles to ES5, making it useful for learning JavaScript internals, as seen in its focused feature implementation.
The README explicitly warns against production use due to ongoing development and incomplete ES6 compliance, making it risky for critical applications.
Only supports destructuring, classes, and arrow functions, with key features like rest parameters and spread operators still on the TODO list, restricting its utility.
Relies on sweet.js, a less common macro system that complicates setup and has poorer ecosystem support compared to mainstream tools like Babel.
Admits features are not fully ES6-compliant, potentially leading to bugs or inconsistencies in edge cases, as noted in the README warning.
