Course Introduction：The answer is: you should first master native JavaScript and then learn the framework. Because frameworks are just tools, JS is the foundation, not understanding JS will make it difficult to troubleshoot bugs and deal with interview questions; understanding native JS can help you better understand the design ideas of the framework; learning to be able to operate DOM, handle events, use Promise, understand this and prototype chains, and write simple interaction functions can start learning the framework; it is recommended to start with HTML CSS native JS first, learn while doing, read more documents, read less quick courses, and write projects by hand.

Course Introduction：Webpack is suitable for large applications, with comprehensive functions but complex configuration; Rollup focuses on packaging libraries, with small output size and strong Tree-shaking; Vite is based on native ES modules, with fast development speed and suitable for modern frameworks. 1. Webpack is centered on "Everything is a module" and supports code segmentation and rich plug-ins. It is suitable for complex projects but slow to build; 2. Rollup supports ESM by default, outputs clean code, suitable for NPM library release, but weakly handles non-JS resources; 3. Vite uses browser native ESM, does not package in the development stage, starts quickly and supports mainstream frameworks, suitable for new projects, but TS and migration support needs to be improved.

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.
