Fixes #
- Single char alternation (e.g. a|b|c|d) in a RegExp can be simplified to use a character class ([abcd]) instead.
This usually also provides slightly better matching performance.
- Character escapes that are replaceable with the unescaped character without a change in meaning. Inside the square brackets of a character class, many escapes are unnecessary that would be necessary outside of a character class. For example the regex [\.] is identical to [.]
- If several qualified expressions occur after the qualifier having been checked for nullable, they can be replaced with optional chaining
I removed the list of individual talks, presentations, and podcasts (maintaining the doc with every new talk is a lot of work, and the list was getting very long). We'll maintain a YouTube playlist with all that info. The playlist and Office Hours playlist are now linked in the "Additional Resources" section (formerly known as "Misc").
Also fixed a few typographical/formatting issues
