JavaScript: Private Static Members, Part 1
By James
A little while ago I talked about creating private variables and methods in JavaScript. This works, but is not necessarily efficient: each instance of the class creates new copies of the members. While that may be exactly what you want for instance variables (think of partNum in the old examples) it is not always ideal.
The complexity jumps significantly, though. So I’m dividing this half into two parts.
To get started, we need to forget about all this Object-Oriented Programming for a minute and look at some of the neat tricks you can do with functions in JavaScript.
