Working with the JavaScript “this” Keyword
JavaScript's "this" keyword can be a bit tricky to work with depending on the context in which it's used. When it's used with patterns such as the Prototype or Revealing Prototype patterns working with "this" can be challenging in some cases. Unlike languages such as C# or Java, "this" can change context. For example, if a Calculator object named calc calls an add() function then "this" represents the Calculator object which means you can easily access any variables defined in the object such as a variable named tax by simply using this.tax.

Using the JavaScript Prototype Property to Structure and Extend Code
There are several different patterns that can be used in JavaScript to structure code and make it more re-useable, more maintainable, and less subject to naming collisions. Patterns like the Revealing Module Pattern, Prototype Pattern, Revealing Prototype Pattern, and others can be used to structure code and avoid what I call “function spaghetti code”. One of my favorite features offered by both the Prototype and the Revealing Prototype patterns is the extensibility they provide. They’re quite flexible especially compared to the Module or Revealing Module patterns out there.
