The document discusses JSON (JavaScript Object Notation), which is a lightweight data format that is easy for both humans and machines to read and write. It uses conventions familiar to programmers and is built upon two basic structures: 1) a collection of name/value pairs (objects) and 2) an ordered list of values (arrays). The document then provides more details on the syntax for objects, arrays, strings, numbers, and how these JSON elements can be nested.

- 3. JSON [JavaScript Object Notation] JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.
- 4. JSON is built on two structures: A collection of name/value pairs. In various languages, this is realized as an object , record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array , vector, list, or sequence.
- 5. JSON is built on two structures: An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma).

- 7. JSON An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma).
- 8. JSON A value can be a string in double quotes, or a number , or true or false or null, or an object or an array . These structures can be nested.
- 9. JSON A string is a collection of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
- 10. JSON A number is very much like a C or Java number, except that the octal and hexadecimal formats are not used.
