{"version":"1.0","type":"rich","title":"ReactJs hook that joins an Array of Elements with a separating Element.","description":"This example demonstrates a React hook that inserts a separator element between each item in an array of JSX elements, producing a new array where the original items and separators alternate. The hook, `useArrayJoin`, uses `useMemo` to cache the result and relies on `Array.reduce` to iterate through the input array, placing the join element—generated by a callback function—between consecutive items. The code specifically leverages React’s JSX type system and the `useMemo` API to optimize re-renders, with the separator receiving a unique key based on the current index.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9b8b26c062a4cf8d976741143049b11d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
