What is JSON?
Abbreviation for JavaScript Object Notation, a text-based data format similar to XML.
It can now be read in most programming languages and can easily be saved to a file or record in a database.
It is widely used because the format is simple, queries are simpler, easier to use and more readable than XML.
Several features of JSON
- Each data information consists of key and value
- Enclosed in brackets {}
- Keys and values must be enclosed in double quotes. If they are enclosed in single quotes, they are not JSON strings.
- Describe multiple data by separating them with commas.
- Keys and values can be written as strings, numbers, logical values (true/ false), blanks (null), arrays, objects.
- JSON files can be saved with any extension, but usually saved with .json or .js extension.
