Using Functions to Initialize and Make Decisions JavaScript (05/31/2007)
(...) The logic is to perform an initialization if it has not already occurred. The function that is called is defined as follows, and it embeds a call to the initialization. Tip You could use this type of code to implement a lazy initialization when writing convention-based code that does not perform an explicit initialization. (...)
