Course Introduction：There are three main ways to detect browser support for HTML5 functions: using Modernizr library, manual detection in native JavaScript, and paying attention to privacy mode and security restrictions. First, the Modernizr library is introduced to add a class that supports features to the tag and provides a JavaScript interface to determine whether the features are available, such as if (Modernizr.canvas). Secondly, native JavaScript detection can check whether an object or method exists, such as using the function support LocalStorage() to detect local storage, or supporting VideoFormat() to detect video format support. Finally, note

Course Introduction：The most direct way to confirm whether the browser supports a certain HTML5 feature is to use JavaScript detection. 1. Use Modernizr for feature detection: After introducing the Modernizr library, it will add the corresponding class to the tag, and can judge the support status through the Modernizr object; 2. Use native JavaScript to detect specific features: check whether there is a certain attribute or method in the global object, such as detecting canvas or localStorage; 3. Check the compatibility data on CanIUse: Visit caniuse.com to obtain the support of HTML5 features by different browsers, assist in decision-making and compatibility plan planning.

Course Introduction：Adapter mode is a structural design mode that allows incompatible interfaces to work together. It converts the interface of the class like a "translator", so that the old system connects with the new library without rewriting the logic. Applicable scenarios include reusing existing classes, unified subclass interfaces, encapsulating third-party APIs, etc. In the implementation, the target object is wrapped by creating an adapter class, calling its methods and converting the interface, such as adapting NewLogger to the OldLogger interface with LoggerAdapter. Unlike appearance mode, adapters focus on interface conversion, while appearance focuses on simplifying complex interfaces. Abuse should be avoided when using it and pay attention to clear naming.

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.
