Knockout is also a perfect choice when you have to reuse a certain part of the model in some other part of the application irrespective of the changing HTML code. Furthermore, if you need to serialize the entire model to JSON so that you can send it over to the server, Knockout is a perfect choice.
On the other hand, jQuery is a perfect choice when there is a lot of Ajax implementations and requests in your program. Moreover, if the application has effects and animations, and a lot of DOM manipulation, jQuery is the best choice to opt for.
Knockout.js use a unique design pattern called MVVM which stands for Model-View-ViewModel. The Model extracts the data from the back-end and represents them visually through UI called View. The ViewModel is an intermediary between the Model and the View that manages binding data, sending data, updating data and data connection. Any change in the backend is automatically reflected in the front end and vice versa. Knockout.js is ideal for data-driven interfaces as in dynamic websites. jQuery is a replacement for an inconsistent DOM API. It is more about manipulating the elements and event handlers. There is no concept of the data model in jQuery. Things get easier with Knockout especially when there is overlapping behavior in the UI. Knockout eliminates the inconsistency that used to be generated using jQuery.
New Features in Knockout.js –
Dependency – Dependency tracking is another awesome feature the Knockout brings on the table. With this feature, your application will automatically update the relevant parts of the UI of the application whenever there is any change in the data model. Therefore, the dependency is maintained, and there is no delay in updating. This helps to maintain the synchronization of the backend and frontend. This is done by using two-way data binding using variables called observables. There is no need to worry about handlers and listeners anymore for tracking the dependency.
Templating – When you are developing a complex application especially when it has the future potential of scalability, you need a proper view model. The template engine of Knockout is native, and you can choose the right template and customize everything for a proper interaction of the data and template.
In fact, this feature also enables the developers to reuse lines of codes in different parts of the application. Moreover, Knockout has integration feature with other libraries and technologies which is why it has become a favorite among developers in a very short time. However, the large section of the community still believes the JQuery has cleaner templates than Knockout.
