+    1. Here, we first import the yup module and define a schema using the object().shape() method. The schema specifies the validation rules for each field in the data object.
+    2. We then create a data object with values for the name, email, and age fields. We use the validate() method of the schema to validate the data against the defined schema. 
+    3. If the data is valid, the validate() method returns the validated data. Otherwise, it throws a validation error with the corresponding error message.
