Development – whether it’s the web, mobile app, or a desktop app – has been intelligently segregated into a client-side and a server-side.
Both frontend and backend have their own set of programming languages and each of these languages has its cult following. The web is full of articles, memes, and jokes praising one language and disparaging the other; so much so that, between a backend developer and the frontend, the banter continues to this day.
User experience is one of the most vital metrics to estimate the ease of use of any application. It not only adds value to the business but lets other important stakeholders project the growth of the business. User experience is directly related to the interface of the application often referred to as User Interface or UI.
One very raw and intuitive way to judge the quality of UI of any application is to find how much does a user needs to interact with UI to accomplish the desired task. The lesser the interaction the better the UI and hence richer user experience.
