Once the state changes, the component renders again. In addition, state can be passed as props to child components too. Of course props may pass down state-like ideas - for example, on a custom input component, I may choose to have a disabled prop which disables some internal text input - but when I say “state”, I’m referring specifically to the state attribute of the component. You may begin to notice a code smell when the state starts to depend on it’s React components are the building blocks of any React application. A React component is simply a JavaScript function that takes an object of arbitrary inputs known as props and returns React elements describing what should be rendered on the UI.

2020-07-30 · It should also be noted that the state is mutable in nature, and should not be accessed from child components. Props. We know that components in React are used again and again in the UI, but we don’t normally render the same component with the same data. Sometimes we need to change the content inside a component.

One of the most confusing topics when first learning React is when to use state vs props. They seem to both do very similiar things, and many times look like State: State can be considered an instance of react component class and is majorly used to communicate with a component.

State object stores values of properties related to a component. When you’re in a development environment, this triggers React to log a warning if the type is different from the one defined. Props can be difficult to keep track of in complex apps, so clearly defining your props as you pass them down is immensely helpful for anyone reading your code.
