在 React 中渲染对象中的所有嵌套对象

我这里有这个对象:

const [generic, setGeneric] = useState ({
    f1: "Hi, Stack Overflow!",
    f2: "Hello!",
  });

我想从中访问所有子对象。
我这里有一些代码,但它不能正常工作:

{Object.keys(generic).map((gen) => (
<>
<h1 key={gen}> 

{/* I also tried rendering files instead of gen, just don't work */}
</>
))

预期结果是:

<h1>Hi, Stack Overflow!</h1>
<h1>Hello</h1>

{Object.entries(generic).map(([key, value]) => (
  
   <h1 key={key}>{value}</h1> 

 ))}

尝试一下

{Object.keys(generic).map((gen,index) => (
  
   <h1 key={index}>{generic[gen]}</h1> 

 ))}
