At a Glance to REACTJS
React can be used in the development of single-page applications and mobile applications. It aims primarily to provide speed, simplicity, and scalability. As a user interface library, React is often used in conjunction with other libraries such as Redux. Moreover, ReactJS development opens new ways and provides a number of possibilities to the developers to make them more creative.
React performs extremely well due to managing a virtual DOM rather than watching and updating the browser’s actual DOM on the fly. Because the virtual DOM is just data rather than rendered content, React is able to efficiently determine what pieces have changed. Once changes are made, the updated DOM can be re-rendered efficiently using features like `request Animation Frame` to ensure optimal performance.
- One-way data flow with props:
Properties (commonly, props) are passed to a component from the parent component. Components receive props as a single set of immutable values. Whenever any prop value changes, the component’s render function is called allowing the component to display the change.
- Two-way data flow with states:
States hold values throughout the component and can be passed to child components through props.
ReactJS facilitates significant data changes which in turn result in an automatic modification in the selected parts of user interfaces. Due to this advanced functionality, you do not need to perform any additional functions to update your user interface.
- Virtual DOM:
Another notable feature is the use of a “virtual Document Object Model”, or “virtual DOM”. React creates an in-memory data structure cache, computes the resulting differences, and then updates the browser’s displayed DOM efficiently. This allows the programmer to write code as if the entire page is rendered on each change, while the React libraries only render subcomponents that actually change.
- Best for SEO:
Most of the times, it has been seen that projects developed on JS are not SEO-friendly. But, with so many improvements and research Facebook has introduced ReactJS. Finally, it stands out from the crowd and allows developers to develop user interfaces that are best to browse on different search engines.
