JSON (JavaScript Object Notation)

JSON – JavaScript Object Notation – is a simple and easy-to-read format used for sharing data. It’s often used to send information between a web server and a web application, usually through APIs or web services.

JSON organizes data using two main structures: objects and arrays. An object is a set of key-value pairs inside curly braces – {}. Each key is a string, and its value can be a number, true/false, null, or another object. An array is a list of values inside square brackets – []. The values can be anything, including other arrays or objects.

JSON is a popular format because it’s easy to understand compared to other formats like XML. Also, it works with many programming languages, especially JavaScript. This makes it a go-to choice for web development.
