Unicode property escapes for different ES versions 2018-2023 #19631
Description
What type of issue is this?
Missing compatibility data
What information was incorrect, unhelpful, or incomplete?
There is a compatibility entry for these escapes at javascript.regular_expressions.unicode_character_class_escape.
That is a single entry, but successive ES versions have added more escapes. Examples can be found in the yearly rules of the eslint-plugin-es-x, such as es-x/no-regexp-unicode-property-escapes-2022.
It would be good to have the support for each different set of escapes be available in the database separately.
What browsers does this problem apply to, if applicable?
No response
What did you expect to see?
Database entries for unicode_character_class_escape_2018, unicode_character_class_escape_2019, etc.
Did you test this? If so, how?
Looked through database files, searched code and issues. Didn't find the information.
Can you link to any release notes, bugs, pull requests, or MDN pages related to this?
Do you have anything more you want to share?
The lack of broken-down data by ES version/year is blocking robatwilliams/es-compat#63
I'm not familiar with the use of these escapes, but it was @ota-meshi who implemented the detection rules in eslint-community/eslint-plugin-es-x#26 and eslint-community/eslint-plugin-es-x#65
