JavaScript RangeError – 基数必须是整数

如果传递 Number.prototype.toString()或BigInt.prototype.toString ()方法的 radix 参数并且不在 2 和36.

信息：

RangeError: invalid argument (Edge)
RangeError: radix must be an integer at least 2
            and no greater than 36 (Firefox)
RangeError: toString() radix argument must be 
            between 2 and 36 (Chrome)

错误类型：

RangeError

错误原因：当 Number.prototype.toString() 或 BigInt.prototype.toString() 方法的可选基数参数指定且不在 2 到 36 之间时，大于 10 的基数开始使用字母字符作为不能大于 36 的数字（因为字母表只有 26 个字母）。

例1：在这个例子中，传递的参数是2，所以没有发生错误。

                      "'Radix must be an" + 
                      " integer' error has not occurred";
                } catch (e) {

                      "'Radix must be an" + 
                      " integer' error has occurred";
                }
            }
        
    

输出：

例2：在这个例子中，传递的参数是0，所以发生了错误。
