2. Lazy Loading in images with React JS 😴 - DEV Community 👩‍💻👨‍💻

Lazy loading is an image optimization strategy that can improve a website’s performance, especially on mobile. It works by delaying the loading of files, such as images, until a user needs them according to their behaviour and navigation.

Projects can be created with: React JS (v 18), Vite JS, TypeScript, CSS vanilla.

With some browsers you can implement lazy loading just by attaching the loading attribute with the value of lazy to your img or frame tag in HTML. For other browsers, an external package, such as this one can be installed and implemented to React applications.

5. React Just Got Even More Awesome 👩‍💻👨‍💻

Finally! A native way to handle async functionality in React. Move over useEffect, now we can fetch our data by simply creating an axios fetch request and wrap it in a use hook.

The use hook is only meant to handle async behaviour, not caching or any other advanced features - so, not a replacement for react-query. It also appears to support conditional execution. This means that we can conditionally fetch data based on some condition.
