react-native - 带参数的函数 React-Native

Question

我有这个功能

export default async function get_happy_songs(param) {

    let emotion = param;
    // console.log(emotion)
    ...

    }

在某些时候我想这样做：

let arg = value;
let happy_songs =  await get_happy_songs(arg);

但是我知道函数定义语法有问题，所以我应该对我的函数做些什么才能获得那个参数？

试试吧，我希望你会发现有用

export async function get_happy_songs(param) {
let emotion = param;
console.log(emotion)
return true
}




 async componentDidMount() {
 
    let happy_songs =  await get_happy_songs('Love you like  you do');
    console.log(happy_songs)
}
