What strategies can be employed for performance optimization in large-scale Vue applications (e.g., lazy loading, code splitting, memoization)?

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. Regularly audit dependencies, replace heavy-duty third-party libraries, and optimize the loading and compression of image and font resources. These strategies can significantly improve application performance using combined.

Go language tutorial manual

Course Elementary 27435

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.

CSS drop cap image, text aligned in white space

I don't think this is an everyday dropcap situation. My capital "S" is an image like this: Note that the actual image extends all the way to the upper column. The top bar is part of the same image, containing the large S and the drawing to the left of the S. I colored the background blue so it can be easily seen here, but the natural color is white. (But ignore the extra gray area at the very top, it's awkward when doing screen captures.) I don't want to ruin the top bar and image. The image provided to me looks like this - a rectangular area with a top bar drawn in the upper right corner and white space below the top bar. I want the text to look like this (
