I'm Daniel Ehrenberg (he/him or they/them), an engineer working in various standards bodies, to improve JavaScript, WebAssembly and the Web Platform. I want to make computers more open and easy to program for everyone.

I work at Bloomberg as a software engineer. Previously, I worked at Igalia, an open source consultancy, which counts Bloomberg among its clients.

To learn about my work, you can watch some of the talks I've given about it. I like to give talks in various groups of JavaScript developers, to explain how TC39 works, encourage people to get involved, and learn more about different developers' needs.

• Conference talks
  • JSConf EU 2018: Native BigInts in JavaScript: A Case Study in TC39
  • BrazilJS 2018: TC39 and elegantly handling missing values in JavaScript
  • WorkerConf 2018: Community-driven language design at TC39 (Pipeline operator)
  • WorkerConf 2019 : JavaScript Class Features: A case study in TC39
  • dotJS 2019: TC39: How we work, what we are working on & how you can get involved
  • Node.TLV 2020: BigDecimal: Avoid rounding errors on decimals in JavaScript
  • FullStackFest 2019: Standardizing JavaScript Decorators in TC39
  • HolyJS Moscow 2020: The future of JavaScript modules: JS module blocks and native bundling
  • NodeFest Japan 2018: Private fields and methods: Coming to JavaScript
  • Alibaba D2 2019: Let's work together on the future of JavaScript through TC39
  • InfoQ GMTC 2019: JavaScript WeakRefs and TC39 standardization
• Meetups/podcasts
  • TC39er
  • TalkScript 32: # is the New _: Private Fields in JS with Rob Palmer
  • dominicode: Etapas de una propuesta en el TC39 con Daniel Ehrenberg
  • WTFront: TC39, el presente y futuro de Javascript
  • BarcelonaJS: TC39: We want your help making the next JS
  • JavaScript Israel: JS Module Blocks and Fragments
  • Various TC39 panels, e.g., at JSConf EU 2019
  • JSKongress 2018 and 2019: Deep Track

I've worked on a number of proposals in TC39, the JavaScript standards committee, including:

• Finished standards (Stage 4):
  • BigInt: Arbitrary-precision integers in JavaScript
  • Class fields and private methods
  • RegExp features: named capture groups lookbehind assertions, Unicode property escapes
  • WeakRefs: Weak references and finalizers
  • Top-level await: Asynchronous module evaluation
• Late-stage proposals (Stage 3):
  • Import assertions and JSON modules: Support for multiple module types in JS
  • Realms: Multiple isolated but synchronously interacting globals in JavaScript
  • Temporal: New date/time library built-in to JS
• Earlier-stage proposals (Stage 1-2):
  • Records and Tuples: Immutable data structures
  • Decorators: Extensible classes
  • Module fragments and module blocks: Inline modules in JavaScript to improve bundling and Web Worker deployment

I've also worked in other areas of standards, including:

• ECMA-402 (Intl): Organized subcommittee and championed several feature proposals
• WebAssembly:
  • Edited the initial WebAssembly JS API and Web API specifications
  • Created the WebAssembly BigInt integration proposal
  • Edited the WebAssembly ESM integration proposal
  • Going forward, I'm really excited about the Wasm GC proposal but haven't managed to help much yet
• HTML (e.g., integrations of TC39 proposals)
• WebIDL (e.g., formalizations)

In a past life at Google, I worked on Linux kernel/firmware stuff to improve access to SSDs. As part of that, I wrote a popular introduction to Linux AIO and even landed some very basic upstream kernel patches.
