I am currently learning React js, and the differences between props and States are apparent.

But will the change in data passed in the prop cause the component to re-render or will it still be static with the data passed initially?

I still have reservations on props values changes, if it does cause a re-render of the component(not changing the data within the components)?

CodePudding user response：

A change in props will cause a re-render.

If you do not want this you can use a state like this:

const Component = (props) => {
  const [firstRenderProps] = useState(props);

firstRenderProps will always have the same value after a re-render
