up when a new entry is added to the cache. The Linkedhashmap class can implement the latter through its Removeeldestentry method. For more complex caches, you must use Java.lang.ref directly.A third common source of memory leaks is listeners and other callbacks.If the client registers callbacks in its own implementation of the API, but does not explicitly unregister, they will accumulate unless some action is taken. The best way to ensure that callbacks are immediately treated as garbage collec

Compared with the previous version, the content of the update is more, overall close to the entire length of 1/2, and this is one of the reasons why the book came to a belated. Specifically, the 5th edition is updated in the following sections: The first part of the chapter on functions

set at the beginning of the instance object creation. objects created from direct amounts of objects use Object.prototype as their prototypes, and objects created by new use the prototype property of the constructor as prototypes. Objects created by Object.create () use the first parameter as a prototype.To detect whether an object is a prototype of another object (or in a prototype chain), use the isPrototypeOf () method.var p={x:1}; // defining a prototype object var o=object.create (p);

two chapters are very abstract and difficult to understand, and the code examples in the book are closely related to the previous content, because the knowledge points in the previous chapters are not thorough enough to understand the code. There is always a need to revisit the textbook to review the previous content to get a little bit of code.Learning progress Bar lines of code (new /Cumulative) Blog volume ( new/cumulative) Learning time (new/cumulative) I
