Course Introduction：The core purpose of a good front-end design is to improve the user experience, make users comfortable to use, find things, and see clearly. 1. A simple and intuitive information architecture requires fewer navigation bars, shallow page levels, and more control of the main menu within 5 items. Combining common icons and text, the mobile terminal prioritizes the bottom operation area. For example, e-commerce websites should highlight search boxes, classification portals and common functions. 2. Visual consistency improves usability. The button style, font size and color need to be unified. Interaction methods such as click feedback and loading animation should also be consistent. Error prompts need to be unified in form and clear and easy to understand. 3. Responsive and clear feedback.

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.
