It is common to see code such as this:

    try {
        // very large block of code here
    } catch (e) {
        // handle exception
    }

This, however, is often a misdesign: in all the statements inside the try block, it frequently happens that only one or two actually throw an exception.

It is therefore advised, both for readability and understandability, to keep try blocks as small and self-contained as possible.
