The properties are data that is passed into a component. These properties are not changed by a client, and their values are always the same. They are assigned to attributes when creating a component. The useState variable represents the initial value of the component’s value. The default value is empty. A value cannot change unless the user inputs new values. React uses one-way binding, so functions and states are pushed from upper-level components to lower-level ones.
React allows developers to use components to build their applications. The components can be reused in other areas and may contain other components. Each component has a render method that specifies how it renders to the DOM. In addition, components can receive props. Props are properties passed by a parent component that specify the values of the component. For example, a parent component can pass a child a property called “react-to” to a component.
React also has various extensions, including React Native. The framework has a rich community and supports a variety of application architectures. Flux, Redux, and React Native are popular frameworks for cross-platform mobile applications. Testing your React application is easy, and Facebook offers a small browser extension that helps developers debug their applications. The heart of React, though, is the concept of components. Components allow developers to break down UI elements into smaller, independent units. Each component has a structure, API, and method.
