Error Handling Review

Great job with handling errors!

In this lesson we went over:

• How mistakes in programming leads to errors.

• Why errors are useful for developers.

• Errors will prevent a program from executing unless it is handled.

• How to create an error using the Error() function.

• How to throw an error object using the throw keyword.

• How to use the try...catch statement to handle thrown errors.

• Evaluating code in a try block to anticipate errors.

• Catching the error in a catch block to allow our program to continue running.

• Why the try...catch statement would be useful in a program.

Now you have the ability to create code that doesn’t break when an error is thrown!

Instructions

If you want to challenge yourself:

• Force different built-in error object to be thrown in a try...catch statement and see when the messages are different.

• Test out what different data types you can throw.

• Use try...catch for a function that accepts user input to allow errors to be thrown but your program to continue running.
