Strstr and Strrstr have been relatively difficult in the string, but as long as we are good at analysis, the anatomy of the string, it will be very easy. In fact, the process of learning code needs us to calm down to analyze, understand. function

In each function, there is a variable named arguments, which holds the parameters of the current invocation in an array-like form. And it's not actually an array, and using the typeof arguments statement tries to return "object", so it can't use a
