How to change a single property of a style component already created using conditional rendering-CodePudding

I got the following code:

function App() {
...
const [message, setMessage] = useState(false);

const styles = {
  backgroundColor:'lightGray',
  ...
}

  return (
         <div>
           <h1> style:{notification ? styles:{styles.backgroundColor:'red'}}>Test</h1>
         </div>
   ) 
}

What I am trying to achieve is just changing the backgroundColor property of the already created style.

CodePudding user response：

function App() {
...
const [message, setMessage] = useState(false);

const styles = {
  backgroundColor:'lightGray',
  ...
}

  return (
         <div>
           <h1> style={notification ? {...styles, backgroundColor: 'red'} : styles}>Test</h1>
         </div>
   ) 
}
