What is useStateAction?
useStateAction is a new React hook that helps developers update state based on the result of a form action.
It acts as a "smart helper" that remembers the state and can update it when a form is submitted.
How to use useStateAction?
To use the hook, developers need to import it from React and then call it in their component.
The hook returns an array with two elements: 'state' (the current form state) and 'formAction' (a new action to be used in the form).
The hook also takes two arguments: 'actionFunction' (the function that runs when the form is submitted) and 'initialState' (the starting value of the state).
When to use useStateAction?
The hook is particularly useful when developers want to update state based on form submissions, especially when using React Server Components, which can provide quicker responses.
The article includes a simple example of using useStateAction to create a counter form, where the count is incremented each time the button is clicked.
