What’s New for JavaScript Developers in ECMAScript 2024

The ECMAScript standard for JavaScript continues to add new language features in a deliberate way.

This year there’s a mix of APIs that standardize common patterns that developers have been writing by hand or importing from third-party libraries — including some aimed specifically at library authors — plus improvements in string handling, regular expressions, multithreading and WebAssembly interoperability.

Meanwhile, the TC39 committee that assesses proposals is also making progress on some of the much larger proposals, like the long-awaited Temporal and Decorators that may be ready for ECMAScript 2025, Ecma vice president Daniel Ehrenberg told The New Stack.

“Looking at what we’ve done over the past year, ECMAScript 2024 is a little similar to ECMAScript 2023 in that it sees smaller features; but meanwhile, we’re building very strongly towards these big features.” Many of those only need “the last finishing touches.”
