What it does
Generate and explain a regular expression from examples of matches and non-matches.
How to use
Give at least three strings that must match and three that must not, plus the regex flavour you target.
Example
/RegexBuild Match: A-1234, B-9999, Z-0001 No match: AB-123, 1234, a-1234 Flavor: JavaScript Want: named capture group for the letter
