hemanth.hm - Apr 2 '22 - - Dev Community

There were several items on the agenda, this post focuses on feature proposals and their progress from the meeting that was held between March 28th-31st, 2022.

Stage 1:

Stage 2:

  • Decorator metadata: Decorators can associate metadata with the value that is being decorated. (P.S: The repo shall be updated with content.)

Stage 3:

  • RegExp set notation + properties of strings: extend the syntax for character classes to add support for set difference/subtraction, set intersection, and nested character classes.

  • Change array by copy: Provides additional methods on Array.prototype and TypedArray.prototype to enable changes on the array by returning a new copy of it with the change.

  • Decorators (sans metadata): Functions called on classes, class elements, or other JavaScript syntax forms during definition.
