An exception handler is a try/catch statement.

Any exception raised in the lines of code included in the try block is handled in the corresponding catch block:

try {
  //lines of code
} catch (e) {

}

e in this example is the exception value.

You can add multiple handlers, that can catch different kinds of errors.
