What is the difference between a JS object literal and a JSON string?

Question

I have confusion about what exactly people mean by Object Literals, JSON, JavaScript Objects, to me they seem similar:

{foo: \'bar\', bar : \'baz\'}

Answer 1

According to the specification, in JSON all strings, whether they are values or keywords, should be surrounded by double quotes.

Your example would be a valid JSON string if it contains the following:

{"foo": "bar", "bar": "baz"}
