Course Introduction：HTML5 is not a programming language, but a markup language. It is used to construct and organize web page content, such as structural arrangement of elements such as text, pictures, and videos, but does not have programming functions such as variable assignment, conditional judgment, loop operations, and function definition. JavaScript is the real implementation of logical functions. Common development combinations include HTML5 CSS3 JavaScript for front-end development; HTML5 JavaScript WebAPI for dynamic interaction effects; and applications in hybrid development frameworks.

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.
