Article Introduction：C's memory management, pointers and templates are core features. 1. Memory management manually allocates and releases memory through new and deletes, and pay attention to the difference between heap and stack. 2. Pointers allow direct operation of memory addresses, and use them with caution. Smart pointers can simplify management. 3. Template implements generic programming, improves code reusability and flexibility, and needs to understand type derivation and specialization.

Article Introduction：The SPA can change content without refreshing the page because it uses JavaScript to dynamically update the local content of the page, and implements it with the help of front-end framework and asynchronous loading technology. Its core mechanisms include: ① Request data from the server through AJAX or FetchAPI; ② Use front-end routes to manage URL changes; ③ Replace part of the content instead of full page overloading in existing pages. This mode is suitable for scenes such as backend management systems, social network interfaces, online editing tools, etc. that require frequent interaction, but attention should be paid to SEO optimization, home screen loading speed, memory management and browser compatibility. During development, it is recommended to use code chunking, evaluate whether SSR or static generation is introduced, and continuously monitor performance to ensure user experience and application stability.

Article Introduction：React is a library and Vue is a framework, which is the most fundamental difference between the two. As a view layer library, React needs to introduce third-party tools to implement routing (react-router) and state management (Redux, MobX), while Vue provides official supporting tools such as VueRouter and Pinia/Vuex as a progressive framework. React uses JSX to write structures in JavaScript, which are flexible but have high learning costs; Vue uses template syntax by default, and the structure and logic are separated, making it more intuitive and easy to learn. The React community has a huge ecosystem but complex choices and a steep learning curve; the Vue document is clear and the API is simple, suitable for rapid development of small and medium-sized projects. Both use virtual DOM, and the performance difference is not

Article Introduction：The steps to obtain data using Axios in Vue components are as follows: 1. Install Axios; 2. Introduce and use Axios to initiate GET requests in the component; 3. Use life cycle hooks to trigger requests; 4. Handle asynchronous operations and state management; 5. Display content based on status in the template. First, install Axios through npm or yarn, then import and configure the data request method in the script part of the component, call the request function using the created hook, use async/await to process the asynchronous process, and set loading and error status to improve the user experience. Finally, in the template, use v-if, v-else-if and v-else instructions to display according to different statuses.

Article Introduction：Using class binding in Vue allows you to dynamically control element class through objects, arrays, or hybrid methods. When using the :class directive, 1. Adding key value to the control class in the object form (such as {active:isActive}); 2. The array form can bind multiple class names (such as [baseClass,sizeClass]); 3. It can mix static classes, objects and ternary expressions (such as ['static-class',{active:isActive}, isSmall?'small-text':'']); 4. Complex logic is recommended to be encapsulated into computed attributes for unified management to improve template clarity and maintenance.

Article 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.

Article 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.

Article Introduction：ESModules (ESM) is the official standard module system of JavaScript, which implements code dependency management through import and export. 1. It provides better code organization and reuse, makes functional modules clearly separated, improves readability and collaboration efficiency, and supports cross-project reuse and avoids naming conflicts; 2. It supports Tree-shaking optimization performance, and build tools can remove unused code and reduce packaging volume; 3. Native support brings a faster development experience, such as Vite uses ESM to enable instant startup of the development server. When using it, you should pay attention to the complete path, the local server environment is required, compatibility issues, and dynamic import should be used. Mainstream frameworks such as React, Vue,

Article Introduction：Customizing the Vue and Element-UI cascading drop-down box template involves the following steps: Understand how the cascading selector works and Vue's slot mechanism. Use scoped-slot in el-cascader to define custom templates. Use node and data variables to get the current node information and the original data. Display data flexibly according to your needs, such as icons or different styles. Note that the data structure complies with Element-UI requirements and use scoped-slot correctly. In conjunction with the state management tool to handle asynchronous data loading. Use browser developer tools to locate issues.

Article Introduction：When developing Vue applications, common anti-patterns include: 1. When dealing with complex logic in the template, the logic should be moved to methods or computed; 2. Abuse of v-if and v-show, and the choice should be reasonably based on the switching frequency; 3. Direct indexing to modify the array or add object attributes to destroy the responsiveness, and the mutation method or $set should be used; 4. Over-necking causes cumbersome communication of components, and state management or provide/inject should be used; 5. Incorrect use of life cycle hooks, attention should be paid to responsibilities at each stage and side effects of cleaning up.

Article Introduction：To make the form field required, you need to ensure that the user cannot submit without filling in it. 1. When using HTML, add the required attribute in the input, select or textarea tags, and the browser will automatically block the submission and prompt; 2. Use JavaScript to implement custom verification logic, block submission by listening to the submit event and calling preventDefault(), and display custom error messages at the same time; 3. In frameworks such as React and Vue, you can directly use the required attribute or combine it with state management for dynamic verification; 4. Server-side verification is essential, whether using backend languages such as Node.js, PHP or Python, etc.
