What is React-use?

React-use is a community-built toolbox of ready-made building blocks for React apps. Normally, React developers write small functions called hooks to handle things like saving data, tracking user actions, or responding to browser events. React-use gives you a huge collection of these hooks out of the box—so instead of reinventing the wheel, you can plug in reliable, reusable logic right away. With React-use, you can:

• Save and load values from local storage without extra code
• Detect when a user is online or offline
• Handle button presses, mouse hovers, or key events easily
• Manage timers, async calls, and other common patterns

Think of it as a Swiss Army knife for React development: it saves time and makes your code cleaner and easier to maintain.
