The second scenario uses the proxy pattern, Among them, the myImage function is only responsible for doing one thing, creating IMG elements and adding them to the page. The loading picture is given to the proxy function ProxyImage to do. When the picture is loaded successfully, the proxy function ProxyImage will notify and execute the method of the myImage function. At the same time, when the proxy object is not needed in the future, we can directly call the method of the ontology object.
The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From Baidu

2. Dynamically add functions to an object and can also dynamically undo them. (Inheritance cannot do this. The function of inheritance is static and cannot be added or deleted dynamically.)
The hotel is close to Yalong Bay, with a first-line sea view. It is very convenient to go to the sea!
"Let 's put it this way, Hit the wasp with ordinary bullets, One shot at most, But it's not the same with drag armour-piercing bombs, As long as it hits the big wasp, The big wasp can burn into a fireball in an instant. Then as long as you touch the same kind around you slightly, You can set them on fire, Let them burn themselves between themselves, Ordinary bullets cannot achieve this effect without this function, In fact, just like the principle of "74 spray", Although the area covered by the burning cannot be compared with the flame tongue emitted by the '74 spray', However, the effective range of traced armour-piercing firebombs is far away. They can be hit at a distance of several hundred meters, which is much stronger than the '74' spray, which takes 30 meters to fire. If you think about it, we can kill them efficiently only when hundreds of big wasps fly to a distance of 30 meters from you. The pressure is not generally large, but quite large.
