JSON
JSON (JavaScript Object Notation) is a lightweight, text-based 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 programming language and is commonly used to transmit data between a server and a web application, as well as for configuration files and data storage. JSON represents data as key-value pairs and arrays, making it highly versatile for structured data.
Developers should learn JSON because it is the de facto standard for data exchange in web APIs, mobile apps, and many modern software systems, enabling seamless communication between different platforms and languages. It is essential for working with RESTful APIs, storing configuration settings, and handling data in applications built with technologies like JavaScript, Python, or Java, due to its simplicity and widespread support across programming languages.
