React is “component-based”, which means the user builds encapsulated components that manage their own state and then composes them to make complex UIs, each of these components can have any amount of “sub-components” which, together with the components, are all re-usable in other components or even in other applications.
To illustrate these “components” let´s look at our LinkedIn page:
Here we have an application with 4 main components, 1. “Profile”, 2. “People also viewed bar”, 3. “Suggested for you” and 4. “Navigation bar”. They all have sub-components, such as the open button in the navigation bar, and were built independently and then articulated together to make this UI.
Another of Its virtues and why it’s called React is because when we change the state of a component, the react element changes and updates the UI. The reason behind this is the use of the virtual DOM, React is able to generate the DOM dynamically, makes the changes in a copy that are stored in its memory, and then compares it with the current version of the DOM, in this way it avoids rendering the entire page every time there are changes, it simply applies the change to the component that has been updated, simple and fast. This leads to a better user experience and impressive performance and fluidity.
Finally, apart from the library itself, another reason to use React is the massive ecosystem that surrounds it within the open-source community, full of supporting libraries to help you get anything done. For example, need a static site, there’s Gatbsy.js. Animations? Spring.js. Forums? Formic and a whole lot of frameworks are developed within the environment to suit your needs.
Today it is essential that all platforms are interactive, visually attractive for users, but above all, they must be functional interfaces. Clearly, this represents a challenge for developers, as they must create platforms based on what the user needs and expects.
