Course Introduction：There are two ways to add JavaScript to HTML: write JS directly in HTML or introduce external JS files. 1. Writing JS directly is suitable for simple scripts or tests, wrapping code with tags, it is recommended to put it in front, or in the defer/async attribute to avoid blocking rendering; 2. External JS files are more common, and are introduced through src to separate HTML and JS, which is convenient for maintenance and reuse; 3. Use async or defer to improve performance. Async is used for scripts that do not rely on DOM, and execute after loading, and then execute in order after defer and other HTML parsing is completed; 4. It is recommended to put scripts in front, if you use defer/async, you can put them, but avoid inserting them into the middle of the body to avoid affecting the rendering stream

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.
