Iterators and generatorsIterators has been used in many programming languages as a-to-more easily work with collections of data. In ECMAScript 6, JavaScript adds iterators as an important feature of the language. When coupled with the new array methods and new types of collections (such as sets and maps), iterators become even more impor Tant for efficient processing of data.In other languages, a walker is used to manipulate data collections more easi

system DLL, Windows File Protection looks for a valid digital signature. • Private DLLs Private DLLs allow programs to avoid being subject to changes to shared DLLs. A private DLL uses version-specific information or an empty. local file to enforce the version of the DLL used by the program. To use a private DLL, locate the DLL in the program root folder. Then, for the new program, add version-specific information to the DLL. For older programs, use an empty. local file. Each method tells the o

-safe. These container classes are platform-independent, that is, they do not have different implementations due to different compilers, and implicit data sharing, sometimes referred to as copy-on-write, is a technique that allows the use of pass-through parameters in container classes without any additional performance penalty. Traversal is an important operation of a container class. The Qt container class provides a Java-like Walker syntax, as well
