Computer science: json, part zero

Tutoring computer science, data structures come up. The tutor mentions json.

The following is my understanding.

json stands for JavaScript object notation. It refers to a format for storing data. json essentially follows the concept of an associative array (see my post here). In particular, a json file may be a comma-separated list of data pairs. The specific format of each pair is “attribute”: value. This pair structure is often referred to as “key”: value, with the attributes being thought of as keys.

The json files I’ve seen start and end with braces. The following could be the contents of a valid json file:

{“age”: 149, “planet”: “Mars”}
