JavaScript Object Notation, commonly known as JSON, is a lightweight data interchange format. It serves as a standard data format used to transmit data between a server and a web application as text. JSON is language-independent, but its syntax closely resembles JavaScript object literal syntax, making it easy for JavaScript to parse and generate data.
JSON is extensively used in web development for exchanging data between a web server and a web application. It’s commonly utilised in combination with JavaScript to parse JSON data received from web servers, and it’s also prevalent in representing configuration data, APIs, and storing complex structured information.
