Errors and exceptions
Handling errors and exceptions is how you write programs that never crash badly but always print nice error messages in case something bad happens.

In every program you’ll have errors, and in every program you’ll have to handle exceptions.

Those errors are raised when an exception happens.

First let’s see which kinds of errors you might get.

We have 8 error objects:

  • Error
  • EvalError
  • RangeError
  • ReferenceError
  • SyntaxError
  • TypeError
  • URIError

Let’s analyze each one of those.

Then we’ll talk about exceptions.
