<h2>Overview</h2>
The <code>useContextSelector</code> library is a powerful tool that enhances the React Context API by addressing the common performance issues associated with re-rendering components when context values change. Traditionally, using <code>useContext</code> means that any change in context triggers a re-render of all consuming components, which can lead to unintended performance hits. With <code>useContextSelector</code>, developers can select specific values from the context that they care about, ensuring that only relevant components re-render when there's a change.
This library introduces an elegant API that is easy to work with, providing functionality to create context selectors that help streamline the performance of React applications. Whether you're building a complex application or just want to optimize the way your components share data, <code>useContextSelector</code> is worth considering.
