React-React-driven AI interactions

Example

Creating reusable components like a 'Button' component that can be used across various parts of an application.

Scenario

In a complex e-commerce application, a developer can create a 'ProductCard' component that displays product information. This component can be reused wherever product listings appear, such as on the homepage, product category pages, or search results.

Example

Using React's declarative syntax to describe the desired UI state with JSX (JavaScript XML).

Scenario

In a to-do list application, the UI displays a list of tasks based on the current state (e.g., 'in-progress', 'completed'). React will automatically update the UI whenever tasks are added, removed, or marked as completed without manually manipulating the DOM.

Example

React compares the previous and current state of the virtual DOM, and only updates the real DOM where changes are detected.

Scenario

In a social media app, when a user 'likes' a post, only the 'like' counter updates without re-rendering the entire feed. The virtual DOM ensures this is done efficiently.

Example

React's 'useState' and 'useEffect' hooks manage state and side effects in functional components.

Scenario

In a weather application, 'useState' can hold the current weather data, and 'useEffect' can be used to fetch new weather data from an API whenever the user enters a new location.

Example

Passing data from parent to child components via props.

Scenario

In a music streaming app, a 'Player' component receives the currently playing song's data as props from a parent 'Playlist' component. The 'Player' then updates the UI to display the current song title, artist, and album art.
