Get to know JSON

JSON is short for JavaScript Object Notation, and is a way to store information in an organized, easy-to-access manner. In a nutshell, it gives us a human-readable collection of data that we can access in a really logical manner.

JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. The official Internet media type for JSON is application/json. JSON filenames use the extension .json.

Common Errors

1. Expecting 'STRING' - You probably have an extra comma at the end of your collection. Something like { "a": "b", } .

2. Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[' - You probably have an extra comma at the end of your list. Something like: ["a", "b", ].

3. Enclosing your collection keys in quotes. Proper format for a collection is { "key": "value" } .

4. Make sure you follow JSON's syntax properly. For example, always use double quotes, always quotify your keys, and remove all callback functions.
