Definitional and how-to posts that help search engines and humans understand RegexLint.
RegexLint lets you paste a regular expression and a test string to get matches plus a plain-English explanation of what the pattern does. It is for developers who want regex to stop being a black box. Use it when you need to confirm what a regex actually matches before shipping it.
A step-by-step for a first regex check using RegexLint: paste the pattern, add a test string, choose flags, then run and read the matches and explanation.
5 recurring errors people make in a regex: unescaped metacharacters, wrong flags, unintended global matches, missing anchors, and unclear intent. Fix each by escaping special characters, picking the right flags, anchoring, and reading the plain-English explanation RegexLint provides.
Trade-offs: speed, cost, and where human review still wins.
