Model-View-ViewModel, data binding and separation of concerns are just some of the reasons that Knockout.js, which I introduced in a recent column ("2 Great JavaScript Data-Binding Libraries," February 2012), has become a popular data-binding library in the Web community.

Knockout supports external templating libraries such as jQuery templates, but, starting with Knockout 2.0.0, it also includes its own native templating engine.

Templating has become second nature to many developers. Whether you use Model-View-Controller (MVC) or XAML or JavaScript, there's often a need to separate a section of structure into its own unit of work or template.

In HTML, it's common to have a structure that you want to repeat in many places. Whenever you see a structure that needs to be reused, templates should pop into your head.

Another common use for templates is in object hierarchies where you need to dive into a list of items and want to use the same structure for each item.

Inevitably your app will pile up the templates and you'll want to keep them in a separate file. Separating the templates into files has a few immediate advantages. First, it can reduce the structure in your main HTML file (less to look at is easier to understand). Second, just-in-time (JIT) templates allow you to grab them as needed and leave the others on the server.

Separates Rails controllers into Policies, Services and Responders.

Meteor is a set of new technologies for building top-quality web apps in a fraction of the time, whether you're an expert developer or just getting started.
