In the modern world of JavaScript development, there are many different frontend frameworks that we can use to write applications, from older frameworks such as Backbone.js, to newer ones such as Angular, React, and Vue. These frameworks will generally use either the Model View Controller (MVC) design pattern, or some variation of it, such as the Model View Presenter (MVP), or Model View View Model (MVVM). When discussing this group of patterns together, they are described by some as Model View Whatever (MVW), or simply MV*.
Some of the benefits of this MV* style of writing applications include modularity and separation of concerns, but one of the biggest advantages is the ability to write testable JavaScript. Using MV* allows us to unit test the Models we use, the Views we use, and the Controllers we use. We can write tests for individual classes, and then extend these tests to cover groups of classes. We can also test our rendering functions and ensure...
