JavaScript Object vs. JSON: What\'s the Difference?

JavaScript Object vs. JSON

Question 1:

• Is the key/property name valid both with and without quotes?

Answer:

Keys can be specified with or without quotes in JavaScript objects. However, keys in JSON strings must be enclosed in double quotes.

Question 2:

• What is the difference between a JavaScript object and JSON?

Answer:

JSON is a data interchange format used to represent data as a string. JavaScript objects are physical types within the JavaScript programming language. When a JavaScript object is converted to JSON using JSON.stringify(), it becomes a string representation of the object's data.

Question 3:

• Is the following method recommended for parsing a JSON string?

var javascriptObj = JSON.parse(jSonString);

Answer:

Yes, this method is recommended for parsing a JSON string in modern browsers. However, for older browsers (before Internet Explorer 8), the json2.js library should be included for support.
