React Context API: Theme Context Tutorial

Create a Theme Context with Custom Colors

Create a Theme Context that manages not only light and dark modes but also allows switching between multiple color schemes.

Expected output: A Theme Context provider that supports multiple themes and a component that switches between them.

Hint: Extend the theme state to include color schemes and update the toggle function accordingly.

Use Theme Context in Multiple Components

Consume the Theme Context in at least two different components and apply theme-based styling.

Expected output: Multiple components reflecting the current theme and updating when toggled.

Hint: Use useContext Hook and apply conditional styles based on the current theme.

React Context API solves the problem of prop drilling by allowing data to be shared globally across components without passing props through every intermediate component.

You consume context in a functional component using the useContext Hook by passing the context object created with React.createContext().

A common use case for Theme Context is managing UI themes such as toggling between light and dark modes across an application.
