new Intl.NumberFormat('en-US', {

}).format(4999.99);

// Output: $4,999.99

Make this dynamic in React:

npm install i18next react-i18next i18next-browser-languagedetector

Create a new file: src/i18n.js

Now let’s set up the main container app.

npx create-react-app app-shell
cd app-shell
npm install -D webpack webpack-cli webpack-dev-server html-webpack-plugin

Key Features:

• Simplicity: Create stores using a straightforward API without the need for reducers or action types.
• Performance: Optimized for performance with selective rendering and minimal re-renders.
• Flexibility: Supports custom hooks, middleware, and integration with other libraries.
• No Providers: Unlike Redux, Zustand doesn't require wrapping your app with context providers.

By wrapping increment and decrement with useCallback, their references remain stable across renders, preventing unnecessary re-renders in child components that receive these functions as props.([GeeksforGeeks][2])

For components that perform heavy computations, useMemo can cache the result of a calculation, recomputing it only when its dependencies change.([Content That Scales][5])
