check if a string is a valid JSON string without using Try/Catch and is a JSON object
V1.2
isJSON(str*, [passObjects=bool])
*with passObjects = true can pass a JSON object in str, default to false
var isJSON = require('is-json');
var good_json = '{"a":"obja","b":[0,1,2],"c":{"d":"some object"}}';
var bad_json = '{"a":"obja""b":[0,1,2],"c":{"d":"some object"}}';
var str_number = '121212';
console.log(isJSON(good_json)); // true
console.log(isJSON(bad_json)); // false
console.log(isJSON(str_number)); // false
// check is an object
var object = {a: 12, b: [1,2,3]};
console.log(isJSON(object, true)); // true
// can use isJSON.strict (uses try/catch) if wants something more robust
console.log(isJSON.strict('{\n "config": 123,\n "test": "abcde" \n}')); // true
