✌️ 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. - 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. Note: Learn more about what the TC39 stages mean here.

✌️ JavaScript Engines Zoo: Learn About Over 100 JS Engines I’m a sucker for a big table of data and this is about as big as it gets when it comes to JavaScript engines. See how various engines compare, sort them by performance, or click on an engine’s name to learn more about its development, history, and end users. The project’s repo also has Dockerfiles for trying each of them out. Ivan Krasilnikov
