What are some edge cases in data validation?
Edge cases in data validation refer to scenarios that occur at the extreme ends of input ranges. For example, validating a date field might require checking for leap years or ensuring that the date is not in the future.
Can you give me more examples of edge cases?
Sure! Other examples include validating email formats, where you might encounter unusual but valid addresses, or checking numeric inputs where values could be negative or zero.
How do I handle these edge cases in my code?
You can handle edge cases by implementing comprehensive validation rules, using regular expressions for formats, and writing unit tests to cover these scenarios.
What tools can help with data validation?
Tools like Joi, Yup, and Validator.js can help with data validation in JavaScript, while libraries like Marshmallow are great for Python.
