For example, did you know it is called React “because it reacts” to challenges users face? Did you know that React is not a framework but appears to work similarly to one? Here are six facts you should know about the JS library.
A library, not a framework
In contrast, frameworks dictate the control flow by calling your code and addressing structural and architectural issues, which React does not do. Instead, React offers methods to aid web developers in managing front-end development more effectively.
Thriving community around React
The React community is known for its strong support and active engagement, reflecting the library’s popularity among developers. React’s official website showcases multiple vibrant communities with a large user base, where members willingly share their expertise, offer valuable advice and assist with code-related inquiries.
Plenty of freely available or highly affordable React resources exist on platforms such as YouTube, Udemy, Coursera and similar websites.
Virtual DOM vs. Real DOM
React developers often come across the term “virtual DOM” and wonder about its advantages compared to the actual DOM (Document Object Model). The virtual DOM is a set of modules that offer a declarative approach to representing the DOM for your application.
Instead of directly updating the DOM when the application state changes, you create a virtual tree that resembles the desired DOM state. The virtual DOM efficiently determines how to update the actual DOM to match the virtual tree without recreating all DOM nodes. A virtual DOM object is a lightweight copy or representation of a DOM object.
React: A supporter of type systems
React provides a built-in feature called propTypes for validating props, allowing components to be organized hierarchically. It is considered good practice to validate prop data types. By declaring propTypes, the code becomes more understandable to other programmers.
When passing in the wrong type, these validators throw errors displayed in the console. React supports various propType validators, including PropTypes.array (for arrays), PropTypes.bool (for booleans), PropTypes.func (for functions) and many more.
