What ECMAScript 2024 and WasmGC Mean for Modern Web Development
The article covers Amazon’s $2 trillion market cap milestone, China’s push to standardize brain‑computer interfaces, the approval of ECMAScript 2024 with new JavaScript features, and Google Sheets’ shift from a JavaScript engine to a WasmGC‑based calculation engine, highlighting their broader tech implications.
Amazon’s Market Value Tops $2 Trillion
According to CNBC, Amazon’s share price rose 3.9% on June 26, pushing its market capitalization above $2 trillion, making it the fifth tech giant to join the “$2 trillion club” after Apple, Microsoft, Alphabet and Nvidia. By mid‑year the stock has gained 27.5 % and Jeff Bezos’s net worth rose, placing him as the world’s second‑richest person.
China Moves to Standardize Brain‑Computer Interfaces
The Ministry of Industry and Information Technology announced the creation of a technical committee to develop standards for brain‑computer interfaces (BCI). The committee will design input/output interfaces, study brain signal encoding/decoding, data communication, visualization, and define a brain‑data file format based on EEG. It will also address AI ethics and safety, and aim to publish standards before other countries.
ECMA Approves ECMAScript 2024
ECMA’s latest meeting ratified the ECMAScript 2024 language specification. Axel Rauschmayer highlighted new features such as grouped synchronous iterables, Promise.withResolvers(), the /v RegExp flag, enhancements to ArrayBuffer and SharedArrayBuffer, string format validation, and Atomics.waitAsync().
Google Sheets Replaces JavaScript Engine with WasmGC
The Google Sheets team discovered a practical use case for WebAssembly garbage collection (WasmGC) and rebuilt its calculation engine in WasmGC, replacing the previous JavaScript implementation. Benchmarks showed the JavaScript engine was over three times slower than the Java version, while the initial WasmGC prototype was about twice as slow as Java. The team expects WasmGC to enable shared‑memory multithreading and improve single‑thread performance in the coming years.
