JSON (JavaScript Object Notation)

JSON (JavaScript Object Notation) is a lightweight data format used for storing and transporting data, commonly used in web applications for data exchange between servers and clients.

JSON (JavaScript Object Notation) is a widely used format for structuring data in a readable and lightweight manner. It is primarily used to transmit data between a server and a web application as text, often in API calls. JSON is language-independent but is particularly well-suited to JavaScript, making it an essential tool for web developers.

JSON structures data in a key-value pair format, where each key is associated with a specific value, similar to how data is stored in dictionaries or objects in various programming languages. Its simplicity and ease of use have made it a preferred alternative to XML for data interchange.

For example, JSON is commonly used in RESTful APIs, where it allows developers to send and receive data in a format that is both easy to generate and parse. This format’s compatibility with JavaScript and other programming languages makes it highly versatile in modern web development.

In summary, JSON is a crucial format for data exchange in web development, offering a lightweight and human-readable way to structure and transmit information between systems.
