What are some examples of schema validation?

Schema validation is a way to ensure that data conforms to a defined structure. For example, in JSON, you can validate that a field is a string or that an array contains only numbers.

Can you give me a specific JSON schema example?

Sure! Here's a simple JSON schema that validates a user object:

{
  "type": "object",
  "properties": {
    "name": { "type": "string" },
    "age": { "type": "integer" },
    "email": { "type": "string", "format": "email" }
  },
  "required": ["name", "age"]
}

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

If the data doesn't match the schema, it will fail validation, and you will typically receive an error message indicating what part of the data is invalid.
