best-practices

You can audit web application security by checking for HTTPS enforcement, configuring Content Security Policy (CSP), validating security headers, sanitizing inputs, and securing cookies to prevent common vulnerabilities and ensure robust protection.

Cross-browser compatibility best practices involve including proper doctype declarations, character encoding, and viewport meta tags, while actively avoiding deprecated APIs to ensure consistent rendering and functionality across major web browsers.

Content Security Policy (CSP) improves web code security by mitigating cross-site scripting and data injection attacks through enforcing restricted resource loading, validating external domains, and applying strict security headers to web applications.

Yes, you can check for deprecated APIs and semantic HTML usage in your codebase to ensure modern web standards, which improves browser compatibility, accessibility, and overall code quality while preventing runtime errors.

The best way to handle event listeners and error handling is by implementing efficient event delegation, properly removing unused listeners, and establishing centralized error management to optimize performance and maintain code quality.

To configure secure cookies and source maps, enforce HttpOnly and Secure attributes on cookies, and properly manage source map configuration to balance production debugging capabilities with security and performance optimizations.
