This extend function, is how Yui Library implements the method of inheriting.Also, note that the last line of the function body
Child.uber = Parent.prototype;
It means setting an Uber property for the sub-object, which points directly to the parent object's prototype property. (Uber is a German word that means "up", "up".) This is equivalent to opening a channel on a
an empty object as the intermediary.
var F = function () {};
F.prototype = Animal.prototype;
Cat.prototype = new F ();
Cat.prototype.constructor = Cat;
F is an empty object, so it hardly accounts for memory. At this point, modifying the cat's prototype object does not affect the animal prototype object.

We encapsulate the above method into a function that is easy to use.

Cat.prototype = new F ();
Cat.prototype.constructor = cat;
In combination with the above two methods, because F is a null object, so almost no memory. Modifying the prototype object of CAT will not affect the prototype object of animal.
Console.log (Animal.prototype.constructor = = animal); TrueThen we encapsulate the above method:
function extend (child, Parent) {
var F = function () {};
F.prototype = Parent.prototype;

a fourth method, using an empty object as the intermediary.
var F = function () {};
F.prototype = Animal.prototype;
Cat.prototype = new F ();
Cat.prototype.constructor = Cat;
F is an empty object, so it hardly accounts for memory. At this point, modifying the cat's prototype object does not affect the animal prototype object.

It returnsThis. When I write a method that doesn't need to return a value, I usually have it returnThis. It allows for a cascade-style of programming.
Next comesInheritsMethod, which indicates that one class inherits from another. It shoshould be called after both classes are defined, but before the inheriting class's methods are added.

the previous method, this method has the advantage of high efficiency (you do not need to create an Animal instance) and saves memory. // disadvantage: Cat. prototype and Animal. prototype now points to the same object, so any pair of // Cat. modifications to prototype are reflected in Animal. in prototype, this is not what we want

You should first think about what problems you are prepared to solve. And whether it's Linux, Android, ARM, C, and so on, I'm here to teach you that every specific technology can not solve the problem alone.S
