Article Introduction：BEM and SMACSS are two structured CSS methods that are suitable for different project requirements. BEM (BlockElementModifier) uses naming rules to clarify component relationships, solve class name conflicts, maintenance difficulties and other problems, and is suitable for component libraries or modular projects; SMACSS (Scalable and Modular Architecture for CSS) structurally divides styles into Base, Layout, Module, State and Theme, which is suitable for hierarchical management of large websites. The two can be used in combination, and the key is to maintain consistency, avoid over-necking, rationalize the use of tools and provide training documents to improve code maintainability and team collaboration efficiency.

Article Introduction：In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

Article Introduction：The most commonly used global attributes in HTML include id, class, style, and title. ①Id is used to uniquely identify elements, often used in JavaScript operations or CSS style settings, and the naming should be semantic; ②class is used to define the same style or behavior for multiple elements, and supports the coexistence of multiple class names, suitable for style reuse; ③style is used for inline style control, suitable for simple or dynamic style settings, but is not recommended to overuse in large projects; ④Title is used to provide mouse hover prompts, suitable for assisting in explaining the functions of elements, but is not suitable for placing key content. Correct use of these properties can improve development efficiency and code maintainability.

Article Introduction：structs are not necessarily faster, performance depends on the scenario. struct is the value type, assignment copy the entire structure, class is the reference type, assignment copy only the reference. The struct is usually allocated on the stack, and the fast but frequent passing of large structures will increase the replication overhead, and the class allocation involves GC pressure on the heap. Small structs are suitable for high-performance and cache-friendly scenarios, and large structs should be avoided or passed with ref/in. The compact memory of the struct array is conducive to caching, and the class array references are scattered to affect efficiency. Scenarios where struct are preferred: small data, short life cycle, no inheritance or virtual methods are required. Avoid using struct scenarios: large structure, complex logic, polymorphic, frequent packing, and sharing

Article Introduction：Hibernate performance optimization needs to start from three aspects: lazy loading, caching, and batch processing. 1. Use lazy loading reasonably, set @OneToOne and @ManyToOne to FetchType.LAZY, and use JOINFETCH to avoid N 1 queries when needed; 2. Enable secondary caching and query caching, add dependencies and configure @Cacheable, suitable for scenarios where data changes less; 3. Set the batch size during batch processing and flush and clear regularly. A large amount of data can be considered for JDBC or StatelessSession to reduce memory consumption.

Article Introduction：There are four ways to create objects in JavaScript, which are suitable for different scenarios. 1. Object literals are suitable for quickly defining small and simple objects; 2. The constructor is used to create multiple objects with the same structure, but the methods will be created repeatedly; 3. Object.create() is suitable for implementing inheritance based on existing objects; 4. The ES6 class provides clearer object-oriented writing, suitable for large projects and inheritance operations. Choosing the right method can improve code efficiency and maintenance.
