Description: 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 is based on a subset of the JavaScript object notation, making it particularly suitable for communication between web applications and servers. JSON uses a structure of key-value pairs, allowing for the representation of complex data in a simple and clear manner. Its minimalist syntax contributes to its popularity in application development, especially in environments where efficiency and speed are crucial. Additionally, JSON is language-independent, meaning it can be used across various programming languages, facilitating interoperability between different systems. The ease of use and readability of JSON have made it the preferred format for data exchange in modern APIs and web applications, where communication between client and server is essential for user experience.
History: JSON was developed by Douglas Crockford in the early 2000s as a data interchange format that could be used in web applications. Its popularity quickly grew due to its simplicity and efficiency, becoming a de facto standard for communication between servers and clients. In 2013, JSON was standardized by ECMA International as ECMA-404.
Uses: JSON is primarily used in web application development for data interchange between client and server. It is common in RESTful APIs, where it is used to send and receive data in a structured format. It is also used in NoSQL databases, such as MongoDB, which store data in JSON format.
Examples: A practical example of JSON is the response from an API that returns information about a user: {“name”: “Juan”, “age”: 30, “city”: “Madrid”}. Another example is the use of JSON in application configuration, where parameters can be defined in a JSON file.
