isJson and primitives

[matthieu88160]

Hi,

I'm using the validator.js as the main validator of form in our company framework. Implementing tests for our component I discovered that the isJson validator doesn't accept the primitives JSON types as valid JSON if they are not encapsulated in an object. Trying to fix it I also discovered that the tests of the validator.js expect these values to be rejected.

Even if these types are not defined as valid types in the initial JSON RFC-4627, the RFC-7159 that obsolete the 4627 strictly defines the four primitives (strings, numbers, booleans, and null) as valid JSON types, making the following valid :

• "null"
• "true"
• "false"

I noticed that "false" is also considered as an invalid JSON regarding the tests.

My question is: is there a good reason to make them invalid?
