How this entity was disambiguated

This entity first appeared as the object of triple T192082 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: ECMAScript
Context triple: [JavaScript, standardizedAs, ECMAScript]

A. JavaScript
JavaScript is a high-level, dynamic programming language primarily used to create interactive and dynamic content on web pages.
B. TypeScript programming language
TypeScript is a statically typed superset of JavaScript that adds optional type annotations and modern language features to improve large-scale application development.
C. WHATWG
WHATWG is a community-driven standards organization that develops and maintains key web technologies, including the living standard for HTML.
D. CoffeeScript
CoffeeScript is a programming language that compiles to JavaScript, offering a more concise, Python- and Ruby-like syntax for writing web application code.
E. WebAssembly specification
The WebAssembly specification is a standardized, low-level binary instruction format designed to enable high-performance, portable code execution on the web and other platforms.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
