흔히 이렇게 알고 있다
JSON.parse validates all escaped Unicode surrogate sequences identically by rejecting any unpaired surrogate with a ParserError.
이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.
컨트랙트
- assert JSON.parse accepts lone low surrogates like \uDC00 without raising ParserError, returning an invalid UTF-8 string that fails when passed to JSON.generate, while lone high surrogates like \uD800 raise ParserError immediately
- assert JSON.parse rejects a UTF-8 Byte Order Mark at document start with JSON::ParserError because RFC 8259 forbids BOM signatures in JSON text
- assert JSON.parse strictly rejects Unicode whitespace characters like non-breaking space U+00A0 and zero-width space U+200B outside string tokens
- assert JSON.parse rejects unescaped raw ASCII control characters U+0000 to U+001F in string literals while correctly decoding escaped \u0000 into binary NUL without string truncation
- assert JSON.parse preserves IEEE 754 negative zero float sign from "-0.0" producing -0.0 whose reciprocal evaluates to -Infinity
