Javascript异步Curry函数ES6

Question

Is there a way to make a curry function async?

Suppose I have the event handler function below (in my actual use case it is not an event handler), how could I update it to run async? My end goal is to have a curried function that I can await (it will be returning a promise).

foo = () => (event) => {
   this.setState({something:event.target.value});
}

Keep in mind the 'await' keyword can only be used inside an async function. So, even if you defined an async function - and you called that function from somewhere else - you won't be able to utilize the 'await' keyword. I believe you're looking for this:

const foo = () => async (event) => {
    await performAnAsyncEvent(event);
    this.setState({something:event.target.value});
}
