A simple hashtable written by JS is mainly used to add URL parameters to the client, such as param1 = value1 & param2 = value2 & param3 = value3. There are some JS frameworks with similar methods, such as the famous prototype framework, and it

Frankfei at 2007/08/02   When learning the locator of objectbuilder, you may know that weakrefdictionary is used as its internal storage structure to implement the object caching mechanism. How is weakrefdictionary implemented? In fact, it uses
