This week’s TC39 meeting: The Ecma TC39 committee (the group behind the design of ECMAScript / JavaScript) met up for the 111th time this week (seen above) to discuss language proposals. The meeting notes won’t be published for a few weeks, but several proposals did see some progress:
Iterator Sequencing progressed to stage 4.
Joint Iteration, Iterator Join, and Await dictionary of Promises go stage 2.7.
Error.captureStackTrace, import .. with {type: “text”}, and Object.keysLength all progressed to stage 2.
The Intl Unit Protocol also reached stage 1 to provide a way to annotate quantities with the units being measured.
Typed Array Find Within progressed to stage 1. Think a native indexOf-type method for TypedArrays.

Tooltip Components Should Not Exist — Dominik challenges some common wisdom in his typically erudite fashion. Stand-alone tooltip components are the wrong abstraction when separated from the underlying UI features that use them. This thinking can apply to many other UI affordances too, so the broad idea is well worth considering.
