How do you handle a try catch error?

It works like this:

1. First, the code in try {…} is executed.
2. If there were no errors, then catch (err) is ignored: the execution reaches the end of try and goes on, skipping catch .
3. If an error occurs, then the try execution is stopped, and control flows to the beginning of catch (err) .
