How can I validate data in Firebase?

You can validate data in Firebase using security rules or by implementing validation logic in your application.

What are security rules in Firebase?

Security rules in Firebase allow you to control access to your database and validate data before it's written.

Can you give me an example of a security rule?

Sure! A simple rule could be: { "rules": { "users": { "$uid": { ".validate": "newData.child('age').isNumber()" } } } } which ensures age is a number.

How do I test these rules?

You can test your security rules using the Firebase Emulator Suite, which allows you to simulate requests.
