Hook that debounces values by discarding inputs that take less than the specified milliseconds between changes.

This example demonstrates a React hook that delays updates to a value until a specified number of milliseconds pass without new input, effectively debouncing rapid changes. The `useDebounce` function takes a `next` value and a delay `ms`, then uses `useState` to store the debounced result and `useEffect` with `setTimeout` to schedule the update, clearing the previous timer via `clearTimeout` when dependencies change. It returns the debounced value, enabling components to ignore frequent intermediate states, such as keystrokes or slider movements, until the user pauses. The code uses only React's core hooks, with no external libraries.

Hook that debounces useState() changes.

This React hook demonstrates how to debounce state updates from `useState` by wrapping the setter in a custom `useStateDebounce` function. It uses `useCallback`, `useRef`, and `useEffect` to manage a `window.setTimeout` and `window.clearTimeout` pair, delaying the `setState` call by a specified `ms` interval. The hook accepts an initial state value and returns the debounced state and setter, preventing rapid re-renders from frequent input changes. The example is implemented as a TypeScript `.tsx` file, showing the logic in isolation without external data sources or visualization libraries.

A interval hook you can use in your ReactJS projects

This example demonstrates a reusable React hook, `useInterval`, that manages a timed callback for animations or periodic updates in a component. It accepts a callback function, a delay in milliseconds, and a dependency list, ensuring the interval resets whenever the callback or dependencies change. The hook relies on React’s `useEffect` and `useMemo` APIs to set up and clear a `setInterval` timer, returning a cleanup function to prevent memory leaks. The code shows a concise pattern for integrating interval-based logic into React projects, suitable for driving data-visualization updates or animations without external libraries.

debouncing input

This example demonstrates a debounced text input for search, showing how user keystrokes trigger an API request only after a pause in typing. It displays the typed text immediately in the input field while delaying the actual search request by 300 milliseconds. The React component uses the `useState` hook to manage both the displayed text and the debounced search value, while `useCallback` wraps lodash’s `debounce` function to stabilize the debounced callback. Each debounced input fires an Axios GET request to the provided `searchPath`, logging the response data to the console. The code illustrates the separation between immediate UI updates and delayed data fetching.

Hook that increments a counter every time useState() is changed.

This example demonstrates a React hook that tracks how many times a component’s state value is updated. The hook, `useStateCount`, returns both the current value and an incrementing counter that increases each time `setValue` is called. It uses React’s `useState` to store a tuple of `[count, value]` and `useCallback` to memoize the update function, depending on the current count. The code is written in TypeScript and shows a pattern for monitoring state changes without external libraries, relying solely on React’s built-in hooks.

Hook that emits the previous and current values of useState()

This example demonstrates a React hook that tracks both the previous and current values of a state variable, returning them as a pair for comparison or animation. The `useStatePair` hook initializes with an undefined previous value and the provided initial state, then uses a `setPair` callback to update the tuple whenever `setValue` is called. It relies on React’s `useState` and `useCallback` APIs to manage the state pair and memoize the update function, ensuring stable references. The code shows a generic pattern for observing state transitions without additional libraries.

Hook that returns the previous value.

This example demonstrates a custom React hook that retains and returns the previous value of a prop or state variable between renders. The hook uses `useRef` to store the current value and `useEffect` to update the ref whenever the value changes, while returning the ref’s previous value from the render. It is written in TypeScript and relies on React’s `useEffect` and `useRef` APIs, showing a common pattern for comparing current and prior values in component logic.

useState

A React counter demonstrates the `useState` hook for managing numeric state, with buttons that increment and decrement a displayed number. The code uses functional updates to avoid stale closures and shows how initial state can be provided either directly or lazily via a function, logging console messages to illustrate when each initialization runs. Rendering uses `ReactDOM.render` into a root div, with the interface styled by large CSS font sizes.

React State Hook example

This example demonstrates a minimal React component that uses the `useState` hook from React 17 to track and display a numeric click counter. It renders a button and a paragraph showing how many times the button has been clicked, with each click updating the state and re-rendering the component. Built with ReactDOM rendering into a root div, the visualization uses `d3.v7` for potential data manipulation but does not directly call any d3 functions. The code shows a simple state-driven interaction rather than a graphical chart.
