View

Why should you avoid catching general errors without filtering for specific error types?

It makes debugging harder
It leads to unreadable code
It may catch unexpected errors and hide bugs
All of the above

What is the best way to handle predictable errors, like user input validation errors?

Ignore them and let the system handle them
Throw custom errors and handle them accordingly
Use general try/catch blocks for everything
Never handle them explicitly

Why is it recommended to use specific error messages in your throw statements?

To confuse attackers
To provide clarity during debugging
To reduce code readability
To ensure the program crashes

When should you use the finally block in error handling?

Always, for every try/catch block
Only when you need to clean up resources
Only if the catch block is not working
You should never use the finally block

What should you do if you catch an error but can't handle it meaningfully?

Ignore the error
Log the error for later debugging and rethrow it
Exit the program
Retry the operation endlessly

What is the risk of catching an error without rethrowing it or handling it properly?

It makes the code more maintainable
It hides the error and may lead to unexpected behavior
It prevents any further errors
There is no risk

Why is it important to avoid using try/catch blocks excessively?

It can slow down code execution
It makes the code cleaner and more readable
It can mask real issues if overused
All of the above

What is a common pitfall of using global error handlers to catch all errors in JavaScript?

It helps in catching every single error
It can prevent the specific handling of different error types
It improves performance
It increases security risks

What is the best practice for error handling in asynchronous code?

Use try/catch blocks in async functions and .catch() for promises
Avoid handling errors in async code
Use await to ignore errors
Catch errors globally in asynchronous code

What should you include in a meaningful error log?

A detailed error message and stack trace
Only the error message
The name of the function
Nothing, error logs are unnecessary
