Is there a simple way to pass all props of a parent component to a child component when using hooks?
It seems to get repetitive sending each state to each component.
I'm wondering if spread operator works and if so what the proper syntax is?
I apologize for not providing an example, had to leave. The example is something to what I'm doing.
const Parent = () => {
const [count, setcount] = useState(0)
const [example, setExample] = useState('')
return (
<Child props={...How to pass all props in the state}
)
}

Conclusion: Use {… Instead, to pass all React props from parent to child at once, you need to take advantage of the spread operator ( ... ). The spread operator lets you pass the entire props object to a child component as that child's props object.
In order to pass the isActive prop from the parent (MyCard) to the child (MyButton), we need to add MyButton as a child of MyCard. So let's import MyButton at the top of the file. import MyButton from "./Button"; Then, let's add MyButton as a child in the return statement of MyCard component.
That's perfectly fine, you're actually supposed to do that.
Just like the state, we can also use props as a dependency to run the side effect. In this case, the side effect will run every time there is a change to the props passed as a dependency. useEffect(() => { // Side Effect }, [props]);
Yes, you can use context API. It was implemented for the same purpose (when passing props down the children's components).
Also, you can do something like below for the class components:
<SomeComponent {...this.props} />
and for functional components:
<SomeComponent {...props} />
