Where can I find examples of invalid json?

Question

JSON

I am writing tests for the JSON parser. Checking for exceptions. But all cases of invalid json according to RFC4627 and RFC7159 are needed. There is documentation, what are the errors
https://developer.mozilla.org/en-US/docs/Web/JavaS...
But unfortunately I don't understand how to get them,
especially like here, what's the difference?
SyntaxError: JSON.parse: unterminated string literal
and SyntaxError
: JSON.parse: unterminated string

Answer 1

Are JSON.parse sources closed?
