JSON Schema

JSON Schema is a tool used to define the structure of JSON data, which is a common format for exchanging information online. Think of it as a blueprint that outlines what data should look like. It specifies the types of data expected, such as numbers, strings, and lists, and can enforce rules like required fields or value ranges. By using JSON Schema, developers ensure that data sent or received in applications meets certain standards, making it easier to validate and understand data consistency, thus improving communication between systems.
