Angular, or in the past AngularJS, is older than React and is the second most popular in our analysis. It was created and is maintained by Google and was developed to address the need for a complete framework that could deal with single-page applications. A single-page application (SPA) is a web application or web site that updates information and data by dynamically rewriting the current page rather than loading entire new pages from a server. Therefore, the application looks more like a desktop PC application but also works well on mobile devices if designed properly. All code is loaded with a single page load, or only partial pages are loaded dynamically when the page is updated. Angular can have a relatively long learning curve as it is really a complete development framework, but Angular itself contains no UI components. Sencha fills that void with pretested, consistently developed UI elements with their ExtAngular product (read our free guide, “When to Choose ExtAngular” to learn more).
This quick-look table may be more useful to you than a technical analysis because it breaks down these three technologies into how they affect a person’s ability to actually get the job done and provides a side-by-side rating and ranking. These ratings and rankings are a matter of opinion and might change based on a developer’s familiarity, coding style, type of design patterns they use, the availability of others around them who can provide help and guidance, and quite likely a hundred other factors.
