javascript - 如何创建和调用接受三个参数(页面长度)并计算 block 面积的 JavaScript 函数

Question

我想编写接受 3 个参数然后返回 block 区域的函数。我已经研究这个问题几天了，但没有答案。我需要一些帮助。

Answer 1

// We declare the function 
var areaOfBlock = function(a,b,c) {
  // we tell it to return to us what it gets
  // when it multiplies a by b and then that answer
  // by c

  // could also be written like:
  // var area = a * b *c;
  // return area;

    return a * b * c;
}
