Course Introduction:The key to optimizing the performance of large Vue applications is resource management, code splitting and rendering efficiency. 1. Use lazy loading to reduce the initial loading time and divide the code blocks by dynamic import; 2. Code splitting at the component level, loading complex or infrequently used components as needed, and grouping code blocks reasonably; 3. Use computing properties, memory technology and v-once instructions to reduce redundant calculations and unnecessary re-rendering; 4.

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.
