Let’s zoom in and see why ReactJS appeals to frontend developers on a large scale:
React Native is the framework for building cross-platform mobile applications using the same codebase. It uses the same design as React which helps you use the rich React library, declarative components, and including mobile UI library.
Unlike AngularJS where the data flow is bi-directional, React supports the unidirectional flow of data. The state is passed from the parents to the child components, but the child cannot update the state coming from the parent React component. The data coming from the parent is called props in React. The unidirectional data flow supported in React has the following advantages:
● Easier to debug as we are aware of where the data is coming from.
● Fewer errors as we have more control over the data
DOM stands for Document Object Model. The virtual DOM is more like a blueprint of the original DOM. Any changes in the DOM will affect the entire hierarchy in the UI page. Any changes made to the virtual DOM is like making the changes in the blueprint. React compares the previous virtual DOM with the updated virtual DOM snapshot and only the latest updated component is changed without affecting the entire UI page and hence improves the app performance.
Now, let’s check and validate why use React over other frameworks?
Let’s understand why React stands to be a better option for web application frontend development as compared to the other frameworks like AngularJS or Vue.
Anyone with basic programming knowledge can master ReactJS. Knowledge of HTML and CSS is sufficient to learn ReactJS.
React follows uni-directional data binding with an architecture called Flux that controls the flow of data from a single point called the dispatcher. With the one-way binding feature of React, it becomes easier to debug the components, especially in large applications.
React can help in building mobile applications (React Native) on iOS, Android, and web at the same time leveraging the concept of code reusability.
Testing in ReactJS is a piece of cake. All the React views can be considered as the functions of the state. These functions can be manipulated to pass as React views to check the output, triggered actions, events, functions, etc.
ReactJS offers a great way to develop a web application-frontend. It is not just simple to learn but also simplifies the web application building and testing process. In short, ReactJS is a component-based, easy to learn, fast, extensive, declarative, frontend development library that is widely adopted and recognized.
