JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
\.(mp4|mov|avi|mkv|webm|m4v|flv|wmv|mpg|mpeg)$   (flags: i)

Raw source: \.(mp4|mov|avi|mkv|webm|m4v|flv|wmv|mpg|mpeg)$

How it works

\. matches the literal dot. The alternation covers the most common video container formats. The trailing $ anchors to end-of-string so we don't match `.mp4` mid-filename. The i flag makes matching case-insensitive (.MOV, .Mp4, etc.).
