This example demonstrates a React hook that continuously cycles through an array of items like a news ticker tape, presenting each value in sequence at a set interval. The hook, `useTickerTape`, takes an iterable and a speed in milliseconds, then maintains the current order of items in state. Using `useEffect` and `setTimeout`, it shifts the first item to the end of the array on each tick, triggering a re-render that displays the rotated list. The code relies on React’s `useState` and `useEffect` APIs, with the array spread operator to create immutable updates.

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.

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 cheatsheet

This animated React cheatsheet presents reusable code patterns for hooks, state management, and component composition. The example uses React hooks including `useState`, `useEffect`, `useRef`, `useReducer`, and `useContext`, alongside custom hooks like `useTimeout` and higher-order components. It demonstrates conditional JSX rendering, callback-based state updates, and the containment pattern via props slots. The animation shows code snippets transitioning between sections, sourced from a gist by abernier.

Repeater triggers the onRepeat event multiple times at the speed interval.

This example demonstrates how a React `Repeater` component triggers its `onRepeat` callback repeatedly at a fixed `speed` interval, simulating a continuous animation loop. The component uses React’s `useEffect` hook to set up a `setInterval` that fires `onRepeat` at the specified millisecond rate, while respecting a `disabled` prop and an optional `emitFirst` flag that triggers the callback once immediately. It renders no visible output, serving purely as a timing utility. The example shows the `Repeater` API in action, where the interval is cleared on unmount or when dependencies change.

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.

Fork of [07] Gauge Chart - Using React Hooks with D3

This example demonstrates a gauge chart built with React Hooks and D3 v5, where users can resize a video element and a draggable container while buttons adjust, filter, or append data values. The gauge renders as an animated SVG arc using `d3.arc` and `d3.pie`, transitioning between states via `transition.attrTween` with `d3.interpolate`. A separate bar chart uses D3 scales and axes with a `ResizeObserver` custom hook to handle dynamic container dimensions. Data updates trigger React state changes, which re-render both visualizations.

JavaScript Array

A animated SVG visualization of a JavaScript array, rendered as a row of circles whose positions and radii oscillate with a sine wave. It uses D3’s `select`, `selectAll`, and `join` to bind data generated by `makeData` to circle elements, updating them at 60 frames per second via `setInterval`. The React framework provides the project structure, while the axis-aligned waveform motion and pulsing sizes are driven by time-varying parameters `t` and the array index.

Basic React Hook Test (Line - Fixed Data)

This example demonstrates a line chart built with React and D3 v5, using fixed sample data stored in component state. The visualization updates interactively when buttons increment every data point or filter out values exceeding a threshold. The code uses D3's `scaleLinear`, `line`, `curveCardinal`, `axisBottom`, and `axisRight` functions to render the SVG. A React `useEffect` hook redraws the chart whenever the state changes, while the `useRef` hook provides direct access to the SVG element for D3 selections.
