Issue with "Regular expression syntax cheatsheet": …

[ColinEberhardt]

MDN URL: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions/Cheatsheet

What information was incorrect, unhelpful, or incomplete?

The MDN cheat sheet uses the term character set to describe the concept that almost all other regex documentation refers to as characters classes

Specific section or headline?

"Character classes"

What did you expect to see?

If you check other sources for regex reference, the regex of the form [xyz], [a-c] are termed character classes. See for example:

https://www.regular-expressions.info/refcharclass.html
TC49 tests: https://github.com/tc39/test262/blob/master/test/built-ins/RegExp/regexp-class-chars.js#L9

However, the MDN cheat sheet calls these character sets

Did you test this? If so, how?

Given we call it Character Classes here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions/Character_Classes and Character set is easily to be confused with the same term used in encoding (https://developer.mozilla.org/en-us/docs/Glossary/character_set), I'm going to change this.

Thanks for your report!
