RFC 8259, "The JavaScript Object Notation (JSON) Data Interchange Format", December 2017

Errata ID: 5218
Status: Reported
Type: Technical

Reported By: Vasiliy Faronov

Section 12 says:

JSON is a subset of JavaScript

It should say:

JSON is nearly a subset of JavaScript

Notes:

JSON is not a subset of JavaScript: there are syntactically valid JSON texts that are not syntactically valid JavaScript. Namely, JSON strings can contain unescaped U+2028 LINE SEPARATOR or U+2029 PARAGRAPH SEPARATOR characters, while JavaScript string literals cannot. Thus, a sequence of characters U+0022 U+2028 U+0022 matches this RFC's 'string' production, but does not match ECMA-262's 'Expression' production.

Section 6 says:

Note that when such software is used, numbers that are integers and
are in the range [-(2**53)+1, (2**53)-1] are interoperable in the
sense that implementations will agree exactly on their numeric
values.

It should say:

Note that when such software is used, numbers that are integers and
are in the range [-(2**53), (2**53)] are interoperable in the
sense that implementations will agree exactly on their numeric
values.

Notes:

The limit is presumably derived from ECMAScript which says:

"The value of Number.MAX_SAFE_INTEGER is the largest integer n such that n and n + 1 are both exactly representable as a Number value"

However, Number.MAX_SAFE_INTEGER is 9007199254740991 ((2*53)-1) making n+1 (2**53) the largest exactly representable Number value
