Here are some key things to know about regex in JavaScript:

You can create a regex pattern using the /pattern/flags syntax, where pattern is the regex pattern and flags are optional flags like g for global matches or i for case-insensitive matches.
You can use methods like string.match(), string.replace(), and string.test() to perform regex operations on strings.
 You can use character classes like [a-zA-Z0-9] to match ranges of characters, and use quantifiers like + or * to match one or more occurrences.
 You can use groups and capturing groups to match and extract specific parts of a string.
 You can use anchors like ^ and $ to match the start and end of a string.
