Four, the problem of the structure function patternThe constructor method works well, but there is a problem of wasting memory.See, we now add a constant property "type" for the Cat object, and then add a method eat (Eat mouse). So, the prototype object cat becomes the following:
function Cat (name,color) {
THIS.name = name;
This.color = color;
This.type = "Cat animal";
This.eat = fun
