  - Add the "@Override" annotation.
    
    Using the @Override annotation is useful for two reasons :
    It elicits a warning from the compiler if the annotated method doesn't actually override anything, as in the case of a misspelling.
    It improves the readability of the source code by making it obvious that methods are overridden.

  - Replace "==" with "===".
    
    The == and != operators do type coercion before comparing values. This is bad because it can mask type errors. For example, it evaluates ' \t\r\n' == 0 as true.
    It is best to always use the side-effect-less === and !== operators instead.
