is-json-object v1.0.2

This is a small package with a minimal footprint that tries to detect if an object is a JSON-like value in the most generic way possible, using the following rules for edge cases

• Though not specified in the standard, root objects may be other values than plain objects
• NaN and Infinitiy are not acceptable JSON values, as per the standard
• Objects constructed with Object.create(null) will be accepted
• Array-like objects with a length property will get accepted

These rules should cover most common use cases, while users requiring more fine-grained contol can take a look at the source (it isn't that much).

Usage

const isJSON = require('is-json-object')

class Foo {  }

isJSON({ a: 1, b: 2 }) // true
isJSON(new Foo) // false
isJSON('test test test') // true
