Immutable updates are crucial in React because it ensures that state changes can be detected correctly, triggering component re-rendering and avoiding side effects. Directly modifying state, such as push or assignment, will cause React to be unable to detect changes. The correct way to do this is to create new objects instead of old objects, such as updating an array or object using the expand operator. For nested structures, you need to copy layer by layer and modify only the target part, such as using multiple expansion operators to deal with deep attributes. Common operations include updating array elements with maps, deleting elements with filters, adding elements with slices or expansion. Tool libraries such as Immer can simplify the process, allowing "seemingly" to modify the original state but generate new copies, but increase project complexity. Key tips include each

Front-end applications should set security headers to improve security, including: 1. Configure basic security headers such as CSP to prevent XSS, X-Content-Type-Options to prevent MIME guessing, X-Frame-Options to prevent click hijacking, X-XSS-Protection to disable old filters, HSTS to force HTTPS; 2. CSP settings should avoid using unsafe-inline and unsafe-eval, use nonce or hash and enable reporting mode testing; 3. HTTPS-related headers include HSTS automatic upgrade request and Referrer-Policy to control Referer; 4. Other recommended headers such as Permis

The data-* attribute is used in HTML to store additional data, and its advantages include that the data is closely related to elements and comply with HTML5 standards. 1. When using it, name it starts with data-, such as data-product-id; 2. It can be accessed through JavaScript's getAttribute or dataset; 3. Best practices include avoiding sensitive information, reasonable naming, paying attention to performance and not replacing state management.

To style SVGs using CSS, you first need to embed SVGs inline into HTML for fine control. 1. Inline SVG allows its internal elements such as or to be directly selected through CSS and to apply styles, while external SVG only supports global styles such as width and height or filters. 2. Use regular CSS syntax such as .class:hover to achieve interactive effects, but use fill instead of color to control the color, and use stroke and stroke-width to control the outline. 3. Use class names to organize styles to avoid duplication and pay attention to naming conflicts and scope management. 4. The SVG style may be inherited from the page, and can be reset through svg*{fill:none;stroke:none;} to avoid

The core of VR web front-end development lies in performance optimization and interactive design. You need to use WebXR to build a basic experience and check device support; choose A-Frame or Three.js framework development; uniformly process input logic of different devices; improve performance by reducing drawing calls, controlling model complexity, and avoiding frequent garbage collection; design UI and interactions that adapt to VR characteristics, such as gaze clicks, controller status recognition and reasonable layout of UI elements.

The core of front-end error monitoring and logging is to discover and locate problems as soon as possible, and avoid user complaints before knowing them. 1. Basic error capture requires the use of window.onerror and window.onunhandledrejection to catch JS exceptions and Promise errors; 2. When selecting the error reporting system, give priority to tools such as Sentry, LogRocket, Bugsnag, and pay attention to SourceMap support, user behavior tracking and grouping statistics functions; 3. The reported content should include browser information, page URL, error stack, user identity and network request failure information; 4. Control the log frequency to avoid log explosion through strategies such as deduplication, current limiting, and hierarchical reporting.
