What are the supported data types by JSON?
Understanding JSON Supported Data Types
JSON (JavaScript Object Notation) is a widely used data-interchange format, especially in web API calls from mobile applications. It supports several fundamental data types that allow for the seamless exchange of information. Let's delve into the supported data types by JSON:
1. Strings: Strings in JSON are represented as a sequence of characters enclosed in double quotes (\"\"). For example, "Hello World" is a string value in JSON.
2. Numbers: JSON supports both integer and floating-point numerical values. Numbers such as 42 or 3.14 can be represented in JSON.
3. Booleans: Booleans in JSON are represented as either true or false, indicating logical values.
4. Null: The null data type in JSON signifies the absence of any value. It is indicated by the keyword 'null'.
5. Arrays: Arrays in JSON are ordered lists of values enclosed in square brackets ([]). For instance, [1, 2, 3] represents an array with three elements.
6. Objects: JSON objects are unordered collections of key-value pairs enclosed in curly brackets ({}). Each pair consists of a key and its corresponding value. For example, {"name": "John", "age": 25} is an object with name and age as keys and their respective values.
It's important to note that JSON does not directly support more complex data types like dates or binary data. However, these can be represented as strings or numbers and then processed accordingly in JSON.
JSON's simplicity and versatility make it a popular choice for data interchange in various applications, particularly in mobile development. By understanding the supported data types, developers can effectively work with JSON data structures and enhance their applications' functionality.
