The problem is the type of quote used in your JSON string, not the outer quotes. The JSON specification only allows for double quoted strings. You could use either type of quote to actually pass your JSON string to the parse()function, though.
问题在于 JSON 字符串中使用的引号类型，而不是外部引号。JSON 规范只允许双引号字符串。不过，您可以使用任一类型的引号将 JSON 字符串实际传递给parse()函数。

The problem is not that your JavaScript string uses "characters but that your JSON strings do not.
问题不在于您的 JavaScript 字符串使用"字符，而在于您的 JSON 字符串没有。
JSON is not JavaScript. JSON strings must be delimited by "characters.
JSON 不是 JavaScript。JSON 字符串必须由"字符分隔。
From the specification:
从规范：
string = quotation-mark *char quotation-mark
and
和
quotation-mark = %x22 ; "

Problem is not with double quoted string, but the json should have no single quotes as delimiters.
问题不在于双引号字符串，而是 json 应该没有单引号作为分隔符。
