Regex Editor & Tester

Matches any single character that is NOT 'T', 'h', or 'e'. Important caveat: the ^ inside brackets negates the character set, so it excludes those three individual letters rather than the whole word 'The'. With the g flag, it finds every occurrence of such characters in the string. Commonly used to illustrate the difference between negated character classes (single chars) and negative lookaheads (excluding whole strings).
