What is schema validation in JSON Schema?

Schema validation in JSON Schema is a way to ensure that JSON data adheres to a defined structure and rules.

Can you give me an example of a JSON Schema?

Sure! Here's a simple example:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "name": { "type": "string" },
    "age": { "type": "integer" }
  },
  "required": ["name", "age"]
}

How does validation work with this schema?

When you validate a JSON object against this schema, it checks if the object has 'name' and 'age' properties and that they are of the correct types.

What happens if the JSON data doesn't match the schema?

If the JSON data doesn't match the schema, the validation fails, and you'll receive an error indicating what is wrong.
