#javascript

There were several items on the agenda, this post focuses on feature proposals and their progress from the meeting that was held between December 14th-15th, 2021.

Stage 4:

Extend TimeZoneName Options: Extend the timeZoneName option in Intl.DateTimeFormat object to support more formatted options.
Intl.DisplayNames v2: Adding more display names to the already favorite DisplayNames object, allowing more "items" to be displayed in a localized manner.

Stage 3:

array-grouping: A proposal to make grouping of array items easier.

Stage 2:

Array.fromAsync: Like Array.from but it converts an async iterable (or a sync iterable of promises) to a promise that will resolve to an array.
RegExp Modifiers: Capability to control a subset of regular expression flags imsx.
RegExp Buffer Boundaries: Buffer Boundaries also allow you to match the start/end of a line and the start/end of the input in a single RegExp using the m flag.

Stage 1:

Intl.Segmenter v2: Unicode segmentation in JavaScript.
