ECMAScript Proposals
Official repository tracking the evolution of the ECMAScript (JavaScript) language standard through its proposal stages.
What is ECMAScript Proposals?
TC39 Proposals is the official GitHub repository that tracks the development and standardization process for new JavaScript (ECMAScript) language features. It serves as a living document cataloging every proposal from initial idea through to final inclusion in the language standard, organized by the TC39 committee's stage process. It solves the problem of fragmented information by providing a single, authoritative source for understanding what new features are being considered, their current status, and their historical discussion.
JavaScript developers, library authors, educators, and browser/engine implementers who need to stay informed about the future direction of the language and potentially contribute to its evolution.
Developers choose this resource because it is the definitive, first-party source for ECMAScript proposal information directly from the standards committee (TC39). Its unique value is the comprehensive, structured, and transparent view it provides into the entire language evolution pipeline, which is not aggregated as completely elsewhere.
