Sounds simple and easily maintainable with the good old class components.
#Finding mouse coordinates react code#
Let’s dive into some code and see the power of hooks in action.Īssume that we would like to be aware of the current mouse position and display it to the user. Hooks let you split larger and harder to understand components into smaller chunks based on each piece’s functionality, rather than the lifecycle method limitations required by the good old classes. It is also observed that classes don’t minify very well, which makes hot reloading very unreliable.Īnother huge advantage is that hooks give you the power to reuse stateful logic and share it among other components without changing your component hierarchy. You have to understand how the “this” keyword works and remember to bind event handlers. Honestly, classes are a little bit confusing and, as the React team states, are a large barrier in learning React. They don’t even work inside class components. Hooks allow you to use state and other React features without writing a class. Let’s find out why we need them, and what problems they solve. Some challenge their effectiveness, some encourage the developers to rewrite the old class components to a functional one as soon as possible. React Hooks became a hype that caught everybody’s attention. In this version, the React team introduced an exciting new feature - Hooks. Since v16.8 stepped up on the web development scene in Feb 2019, the React world changed dramatically.
