如何创建和调用接受三个参数（页面长度）的JavaScript函数并计算块的面积

Question

我想编写接受3个参数并返回块的区域的函数。我已经研究了几天，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; 
}
