ReactJS is an open source JavaScript library designed by Facebook for creating rich and engaging web apps fast and efficiently with minimal coding. The core objective of ReactJS is providing the best possible rendering performance. Its strength comes from the focus on individual components. Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.
Uses of ReactJS and its popularity
While other technologies such as Angular were available when Facebook developed ReactJS, most developers were forced to do a lot of coding. Developers using other frameworks have the challenge of having to rework on most codes even when crafting components that changed frequently. What they wanted was a framework that could allow them to break down complex components and reuse the codes to complete their projects faster.
ReactJS provided the solution that developers were looking for. It uses JSX (a unique syntax that allows HTML quotes as well as HTML tag syntax application for rendering specific subcomponents) This is very helpful in promoting construction of machine-readable codes and at the same time compounding components into a single-time verifiable file.
Today, ReactJS has become highly popular because of its extra simplicity and flexibility. Many people are even referring to it as the future of web development. It is estimated that more than 1,300 developers and over 94,000 sites utilize ReactJS.
Part of this huge popularity comes from the fact that top corporations such as Facebook, PayPal, Uber, Instagram, and Airbnb use it to solve user interface related issues. This credibility has drawn a lot of people to the framework.
Why most people prefer to use ReactJS
- It allows developers to write their apps within JavaScript. JSX is one of the greatest features that not only makes ReactJS easy but fun too. Developers can easily make a new UI feature and see it appear in real time. It brings HTML directly into your JS.
- Components allow developers to break down complex UI. The idea of components is what makes ReactJS unique. Instead of worrying about the entire web app, it makes it possible to break the complex UI/UX development into simpler components. This is crucial in making every component more intuitive.
- The Props make it possible to populate components using custom data. Pros in ReactJS make it possible to pass the custom data to a specific UI component. This is a great way of filling a blank when rendering JSX components.
- The State makes it possible to store all the changes in one section. When using ReactJS, developers take all the content that can change during the application and place it in a single location (State). With state, single web application becomes very simple because all the details are sourced from one section.
- It uses Virtual DOM that makes the app fast. When ReactJS was crafted, the designers rightly predicted that updating old HTML would become extra crucial and expensive. Therefore, the idea of Virtual DOM helps allows ReactJS to know when exactly to re-render or when to ignore some specific pieces of DOM because it can detect when the data has changed. A UI that reacts promptly is crucial in enhancing the user experience.
