The example below shows how to create a module, namespace // it, and specify public/private properties and functions. // Be aware that the Module Pattern is NOT generally used for object-oriented // programming.

The design pattern below is only one of many useful patterns that can help you level up as a JavaScript developer. For the full set, see JavaScript Design Patterns . JavaScript modules are the most prevalently used design patterns for keeping particular pieces of code independent of other components. The Module Pattern is one of the most common design patterns used in JavaScript and for good reason. The module pattern is easy to use and creates encapsulation of our code.
