How to Add current i's value of for loop into an empty array state in react functional componen-CodePudding

    const [btn, setBtn] = useState([]);
    let newArray = []
    for (let i = 1; i<=10; i  ) {
      newArray.push(i);
      console.log(btn);
      setBtn([...btn,...newArray])
    }

i have tried to add newArray to state by using the spred operatar but this will result into an infinite loop and my react app is crashed and after geeting the 1 to 10 value in my btn array i need to use loop over my btn array state.*

CodePudding user response：

put it inside useEffect

const [btn, setBtn] = useState([]);

useEffect(() => { 
    const newArray = []
    for (let i = 1; i<=10; i  ) {
      newArray.push(i); 
      setBtn([...btn,...newArray]) 
    }
}, [])
