To update the parent's state in React without using Redux, you can use a technique called 'context API' or 'react hooks'. Since props are immutable, you cannot directly access and modify a child component's state from its parent. However, you can use context API to share data between components.
💡 How to Use Context API
- Firstly, you need to create a context. Create a new file `Context.js` and add the following code:
Method 1: Context API
- Step 1: Create a context. Use the `createContext` function from `react` library to create a new context.

By using context API, you can easily share data between components without having to pass props down manually.
