如何输入此功能的值并输出(输入值的)功率

Question

代码代码段：问题：在浏览器控制台上返回"未定义"，如何获取代码输入A和B并输出功率？

var a = 0;
var b = 0;
function power(a,b)
{
    if (b === 0) {
        console.log("power = 1");
    } else if (b === 1) {
        console.log("power = a");
    } else {
        return math.power(a, b-1);
    }
    console.log("Power");
}

Answer 1

您是否使用所需值调用您的功能？即

power(a,b);

Answer 2

var a = 0;
var b = 0;
function power(a,b)
{
    if (b === 0) {
        console.log("power = 1");
    } else if (b === 1) {
        console.log("power = a");
    } else {
        return math.power(a, b-1);
    }
    console.log("Power");
}
//call function 
power(a,b);
