如何控制台记录答案而不是整个函数(Javascript,ES6)

How to console log the answer instead of whole function (Javascript, ES6)

我正在编写一些 ES6 代码,我想 console.log 或 document.write 我的函数的答案。当我尝试这样做时,它会写入整个函数。有没有简单的方法来做到这一点?

const stats = {
  max: 56.78,
  standard_deviation: 4.34,
  median: 34.54,
  mode: 23.87,
  min: -0.75,
  average: 35.85
};

const half = ({max, min}) => (max+min) / 2.0; 

document.write(half)

您只需使用括号调用函数(并将 stats 对象作为参数传递):

const stats = {
 max: 56.78,
 standard_deviation: 4.34,
 median: 34.54,
 mode: 23.87,
 min: -0.75,
 average: 35.85
};

const half = ({max, min}) => (max+min) / 2.0; 

document.write(half(stats))
