Beginner to React, I have multiple state variables:
function ParentComp(){
const [firstName, setFirstName] = useState("")
const [lastName, setLastName] = useState("")
const [address, setAddress] = useState("")
return <p>Bonjour</p>
}
Of course I can pass them to the child components like this:
<ChildComponent firstName = {firstName} setFirstName = {setFirstName}
lastName = {lastName} setLastName = {setLastName}
address = {address} setAddress = {setAddress}/>
But I have many more state variables, and actually I want to pass them to the child of the ChildComponent. Is there a way to wrap them in a array or object somehow? I googled and found "context api" but I'd like a more beginner friendly solution.
You can do something like this if you want to keep them as separate states
<ChildComponent {
...{
firstName,
lastName,
address,
setFirstName,
setLastName,
setAddress
}
} />
Otherwise, you coud use useReducer
for easier updates to the state and you will get a single object with all states and one update action.
