Advancing from jQuery to AngularJS
Technology trends are increasingly growing today with the developers building robust and more complex applications. Almost all of the rich web applications that we currently see on the web rely on a subtle set of UI controls, libraries and frameworks. There are so many options out there to provide a consistent, reliable, and highly interactive user interface, but selecting the right library or a framework can be overwhelming. To have an idea of all the possible alternatives, in this article we will explore what constitutes best practices with regard to jQuery and, furthermore, why angular is a good choice of a framework to implement.
Let say, if you would like to send some requests to a backend server and display the results on a web page and vice versa. We can perform this simply in both Angular and jQuery. But with Angular it goes really well against jQuery with one big difference. It does not involve us to think of the back and forth DOM translations as opulent to jQuery. In jQuery, the view and the logic or behavior which affects those elements is left to the developer to split them. In jQuery, if we wish to update a specific DOM element with backend data it has to be coded. There is no separation as to which is the data and which is the controller of the data.
That’s where AngularJS comes into play with its two way data binding. Angular separates the UI data and the UI representation of data. The code in AngularJS is the translation of data to the DOM and vice versa. Angular makes this binding ideal, while increasing productivity. This is the best way to separate data and the HTML view code.
Angular provides rich ‘desktop like’ applications and features that you don’t get with using a jQuery library.
- MVW pattern (similar to MVC)
- Two way data binding
- Dependency Injection:
- Form Validations
- Deep Linking for dynamic pages
- Communication with server
- Reusable components and localization to name a few
When looking for a comprehensive all-in-one solution, AngularJS is the right choice between the two. Its two-way data binding, in-built directives and filters allows developers to build applications very rapidly. So if you are looking for a lightweight and modular front-end framework for developing fast and powerful web interfaces, AngularJS is the apt framework to build complex applications. I hope this post has made you think about Angular.js as being a more than viable replacement to jQuery.
