Do React Hooks replace render props?
Hooks can replace some render props, but not all. Hooks can’t render anything, they can’t set values in the context (although they can consume values), and they can’t implement error bounds. Given these limitations, you may still find yourself using render plugins from time to time.

Is it okay to call Hooks inside loops or conditions?
Do not call Hooks inside loops, conditions, or nested functions. Instead, always use Hooks at the top level of your React function, before any early returns. By following this rule, you ensure that the hooks are called in the same order each time a component is rendered.
How to pass callback function in React hook?
x, if you want to invoke a callback function on state change using the useState hook, you can use the useEffect hook attached to the state change. import React, {useEffect} from “react”; useEffect(() => { props.

Where do you call a hook in react?
The React Hooks rules clearly state: Do not call Hooks inside loops, conditions, or nested functions. Instead, always use Hooks at the top level of your React function. React Hooks must be called in the same order each time the component is rendered.
What is the best way to prevent callbacks in react?
You can see the same pattern here: on every render, a new instance of the callback function is created, which is unnecessary. The best way to avoid that inside a functional stateless component is to use the React.useCallback hook.
Can you rewrite classes to hook into react?
We don’t recommend rewriting your existing classes in Hooks unless you’ve planned to rewrite them anyway (for example, to fix bugs). You can’t use Hooks inside a class component, but you can definitely mix classes and function components with Hooks in a single tree.
What is the difference between render props and hooks?
Often rendering props and higher-order components render only a child. We think hooks are a simpler way to serve this use case. There is still a place for both patterns (for example, a virtual scroll component can have a renderItem property, or a visual container component can have its own DOM structure).
