Which of the following is NOT a data type that JSON can represent?

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It supports a limited number of data types.

The correct answer is associated with the term "dictionary," which is not a data type that JSON directly represents. In JSON terminology, what is often referred to as a "dictionary" in other programming languages, such as Python, is actually represented as an "object" in JSON. An object in JSON is defined using curly braces {} and consists of key-value pairs, where the keys are strings.

The other data types are well-defined within JSON:

• Strings are used to represent textual data and are enclosed in double quotes.

• Arrays represent ordered lists of values and are enclosed in square brackets [].

• Numbers represent numeric values and can be integers or floating-point.

Understanding these distinctions is crucial for effectively using JSON in programming and APIs, where accurate data representation is vital for communication between systems.
