One must not forget JSON (JavaScript Object Notation) had to be Javascript compatible. It was almost. That is one of the main features. It could be eval'ed back into JS object after all. > Although Douglas Crockford originally asserted that JSON is a strict subset of JavaScript, his specification actually allows valid JSON documents that are not valid JavaScript; JSON allows the Unicode line terminators U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR to appear unescaped in quoted strings. > JSON is a strict subset of ECMAScript as of the language's 2019 revision. https://en.m.wikipedia.org/wiki/JSON#Data_portability_issues https://en.m.wikipedia.org/wiki/JSON#Data_portability_issues
