Course Introduction：Detailed explanation of jQuery module pattern: build maintainable and extensible plug-ins Core points: jQuery's module pattern can organize code in a maintainable and extensible way, keeping the global namespace neat, reducing the possibility of naming conflicts, and providing ways to protect variables and methods. Create a basic jQuery plugin using module pattern by defining a self-executing anonymous function to encapsulate the plugin code, providing private scope for variables and methods, and then exposing the public API by returning objects containing public methods and attributes. Module pattern is a design pattern that can be used not only with jQuery but also with any JavaScript library, and can be used to develop commercially for jQ

Course Introduction：1. Use modules in the Python standard library to efficiently implement common data structures and algorithms. 2. The collections module provides such as deque for queues and stacks, counter for frequency statistics, and defaultdict for convenient grouping. 3. The heapq module can be used to implement heap structure and is suitable for priority queues and sorting tasks. 4. The bisect module supports efficient search and insertion operations, which is suitable for maintaining ordered lists. These tools not only improve code efficiency, but also reduce the possibility of errors.

Course Introduction：Asynchronous JavaScript module refers to modules loaded in a non-blocking manner. They are loaded on demand through dynamic import (Dynamic Import), thereby improving application performance. 1. The asynchronous module adopts the import('module-path') syntax, returns the Promise, allowing the module to be loaded on demand during runtime; 2. It is suitable for functions, conditional loading, lazy loading and other scenarios triggered by user operations, such as loading the image editing module after clicking the button; 3. Pay attention to loading timing, error handling, cache mechanism and packaging tool support when using it; 4. Best practices include dynamic import of non-core functions, cooperating with loading prompts, avoiding duplicate loading, and can multiplex logic through encapsulation loader.

Course Introduction：Yes, PhpStorm can be used for Java project development. 1) Configure JDK: File->ProjectStructure->SDKs->AddNewSDK->JDK, select the JDK path. 2) Create a Java module: File->New->Module->Java, select the Java version. 3) PhpStorm provides syntax highlighting and code prompts, but its Java support is not as perfect as IntelliJIDEA, and the interface and shortcut keys are more suitable for PHP developers.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
