JavaScript Module pattern for Java Developers -- Part 1
Lately I have spent some time figuring out what a JavaScript Module pattern is as well as its purpose. After that I decided to write down the nitty-gritty. Let's take a simple example of a Java BankAccount class. It has two private fields to store the owner of an account and its balance.
