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.

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.

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.

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.

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.

Hook that records the history of state changes as an Array buffer upto a certain length.

A React hook records state changes as an array buffer capped at a specified length. The hook initializes with a single state value and appends each new update, trimming older entries to maintain the size limit via array slicing. It uses React’s `useState` to store the history and `useCallback` to memoize the update function. This example demonstrates a generic TypeScript utility for tracking state evolution, with no rendering or visualization logic included.

React Starter

This example demonstrates a React component that displays the current value of a counter alongside the value from the previous render using the `useState`, `useRef`, and `useEffect` hooks. The code uses React’s `ReactDOM.render` to mount the component into the `#root` element defined in `index.html`. A custom `prevCountRef` stores the value from the previous state update, which is then displayed in the header. The counter starts at 20 and shows the before/after values on each render.

On click increment[count and setcount]

This example demonstrates a simple counter interface with a button and a display. Clicking the button increments a numeric count value shown in a large paragraph element, with the current total displayed in the text "click the button {count}". The implementation uses React's `useState` hook to manage the count state and `setcount` to update it, while the `onClick` event handler triggers the increment function. The interface is rendered via ReactDOM's `render` method into a root div, with styling applied through embedded CSS that enlarges the text and button for visual emphasis.

A hook that persists useState() to localStorage.

This example demonstrates a custom React hook that synchronizes a component’s state with the browser’s localStorage, enabling persistent data across page reloads. The hook, `useStateStorage`, initializes state with a provided default value and reads any stored JSON from localStorage on mount, updating the state if valid. It exposes a setter function that writes both the new state and its JSON-serialized form to localStorage. The code uses React’s `useState`, `useEffect`, and `useCallback` APIs to manage lifecycle and memoization, while leveraging `localStorage.getItem` and `localStorage.setItem` for storage operations.
