Embarking on a career in the tech world offers a lot of exciting opportunities and different landscapes. However, choosing the right path to pursue is integral. React JS emerges as an excellent choice for beginners who are planning to jump into the field of web development.
Local to the component: State is managed within the component (similar to variables declared within a function). It’s private and fully controlled by the component.
Mutable: State can be changed, usually in response to user actions or system events. Changing state triggers a rerender of the component, which updates the UI.
Initialization and update: State is initialized in the constructor of a class component or by using the useState Hook inside the functional components. It’s updated using the `setState` method in the class components or the setter function returned by the useState Hook inside the functional components.
Use cases: State is used for data that changes over time, like user inputs, timer values, or data fetched from an API.
Short for properties: Props are read-only configurations that are passed to a component by its parent.
Immutable: Props cannot be modified by the component that receives them. They are intended to provide fixed values and callback functions to components.
Pass data down the component tree: Props are the primary means of passing data from parent components to child components, enabling components to be reused with different data.
Use cases: Props are used for static data that the component receives from its parent, like configuration options or the initial data for rendering.
