JSSupported

JavaScript / ECMAScript

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

PYSupported

Python (re)

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

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
"([^"\\]+)"\s*:\s*("[^"\\]*"|-?\d+(?:\.\d+)?|true|false|null)   (flags: g)

Raw source: "([^"\\]+)"\s*:\s*("[^"\\]*"|-?\d+(?:\.\d+)?|true|false|null)

How it works

"([^"\\]+)" captures the key — non-quote, non-backslash chars (so escaped quotes break the match — by design, this is a quick parser, not a strict one). \s*:\s* matches the separator. The value group covers strings, signed integers/decimals, true, false, and null. Use a real JSON parser for production!
