reactjs_如何从API获取的值显示到ReactJS页面中

let resultofapi被全局声明，我使用从API接收的值对其进行了初始化。我想将该值显示在我的react js页面（在表中）。当我在API内打印值时，它返回我输出"similarity_score":0.9999999404。但是当我在API之外访问它时，它给了我value = undefine

pd.usage()
.then(respOnse=>
console.log(response);
)
.catch(error =>
console.log(error);
);
**pd.semantic(
pd
.semantic(textarea1, textarea2)//these are forms data
.then(respOnse=>
console.log(response); //output="similarity_score":0.670276463
*resultofapi = response;* //output=resultofapi="similarity_score":0.670276463*
)**
.catch(error =>
console.log(error);
)
)
.then(respOnse=>
console.log(response);
)
.catch(error =>
console.log(error);
);
console.log(resultofapi)//output=undefined
