ECMAScript 2024, the latest version of ECMA International’s standard for JavaScript, has been officially approved, with features including transferring ArrayBuffers and advanced capabilities for working with string sets.
The ECMAScript 2024 specification, also generally known as ECMA-262, was approved on June 26. Among the features are added facilities for resizing and transferring ArrayBuffers and SharedArrayBuffers. ArrayBuffers have previously enabled in-memory handling of binary data. The new feature extends ArrayBuffer constructors to take an additional maximum length that allows in-place growth and shrinking of buffers. SharedArrayBuffer was also extended to take an additional maximum length that allows in-place growth.
