do I need to use adapter mode?when developing an application, you will often need to replace one of these parts, for example, a library that you use to save logs or similar content. When you replace it with a new library, the new library is unlikely to have exactly the same interface. From here, you have two choices:(1) Check all the code and change all the code that points to the old library.(2) Create an adapter so that the new library can use the

Many events in the recent development are triggered frequently, and the same data is called in the background every time the event is triggered because there is no cache processing. These days I suddenly realized that my code has a lot of space to optimize, and then think of the closure can have the function of caching, so it was deeply researched to facilitate the optimization of the previously written code. After completing the optimization, write t

JavaScript events are a series of actions caused by users accessing Web pages, such as clicking the mouse, tapping the keyboard, and so on. When a user performs a similar operation, it triggers the execution of a series of code as a response to the user's actions, which is called an event.Events are typically used for browser and user interaction, and we usually divide the event model in JavaScript into thr
