A withdrawn TC39 ECMAScript proposal introducing deeply immutable Record and Tuple value types to JavaScript, with spec text, tutorial, and cookbook. The proposal reached Stage 2 but was officially withdrawn, so it is now a historical reference document.

Use cases

• understand how immutable records and tuples would work in javascript
• research the history of the tc39 record and tuple proposal
• study ecmascript language specification design for value types
• compare built-in immutability against libraries like immutable.js
• learn why deeply immutable data structures were proposed for javascript

When to choose

• you need the official spec text, tutorial, or cookbook for the Record & Tuple proposal
• you are researching TC39 proposal history or why this proposal was withdrawn
• you want to study language design for immutable compound primitives

When to avoid

• you want immutable data structures to use in production JavaScript today - use userland libraries like Immutable.js instead
• you expect this to become part of the JavaScript language - it has been withdrawn
• you need a runnable library or polyfill - this repository is a specification document
