List of Questions5 questions
- Question 1
- Assume that testing is more important than input validation.
- Assume all arguments are always of the correct type and value.
- Assume that all function arguments may be of the wrong type or value.
- Assume that all inputs should be manually verified by the user.
- Question 2
- It must be a string with a length of at least 2.
- It must be an array.
- It must contain only uppercase letters.
- It must be a number.
- Question 3
- Always return a default value regardless of input.
- Only log errors for later review.
- Ignore the validity of inputs completely.
- Implement checks to ensure inputs meet specific criteria.
- Question 4
- A default value should be returned without informing the user.
- An appropriate error message should be triggered.
- The program should crash to alert the developer.
- The function should proceed with processing anyway.
- Question 5
- They allow the function's main logic to execute only if input conditions are satisfied.
- They eliminate the need for any error handling.
- They replace the need for input validation checks.
- They make the code less readable and harder to maintain.
