Course Introduction：Using CSSGrid is the best way to create a responsive image library. 1. Use CSSGrid layout to implement adaptive grids through display:grid, grid-template-columns:repeat(auto-fit,minmax(200px,1fr)) and gap; 2. Optionally add media queries to accurately control the number of columns at different breakpoints, such as the small screen set to 1 column and the flat panel set to 2 columns; 3. Optimize image performance, adjust the size reasonably, use WebP format and combine srcset to achieve responsive loading; in addition, you can try multi-column layout to simulate the waterfall flow effect, but it is recommended to use the main Grid solution, which does not require JavaScript, is highly adaptable and dimensional.

Course Introduction：Common Vue performance anti-patterns include: 1. unnecessary responsive data, 2. Frequent execution of functions in templates, 3. Abuse of v-if and v-show, 4. Component communication over-reliance on $emit and $root/$parent, 5. Ignore the correct use of key attributes; the corresponding optimization suggestions are: only set the really needed data as responsive and use Object.freeze(), replace template functions with computed attributes, use v-show to switch high-frequency v-if, use state management library to reduce coupling, and always use unique identifiers as key.

Course Introduction：The key to managing subscriptions in Vue components is to avoid memory leaks and duplicate triggers. Three key points need to be followed: 1. Use beforeUnmount or onBeforeUnmount to clean up the subscription; 2. Avoid creating new subscriptions directly in the template; 3. Encapsulate subscription logic with composable functions for reuse and unified management. By unsubscribing before component uninstallation, moving subscription logic out of templates and saving to responsive data, and encapsulating common logic, performance and maintenance can be effectively improved, ensuring "who creates and cleanses", thus preventing memory leaks and unexpected behaviors.

Course Introduction：Organizational logic centrally manages related logic according to function rather than option type; 2. Create custom composables starting with use to encapsulate reusable responsive logic to improve consistency and maintenance; 3. Use composables to combine ref or Pinia to manage global state, use ref for small projects, and use Pinia to implement modular state management; 4. Use syntax to reduce template code to improve readability and development efficiency; finally, by extracting logic and reusing composables to achieve scalable, easy to test, and easy to maintain Vue3 application architecture, which is recommended for building medium and large projects.

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.
