A deep dive into the security model of JavaScript module expressions, focusing on dynamic module loading and best practices for building secure and robust applications. Learn about isolation, integrity, and vulnerability mitigation.

JavaScript Module Expression Security Model: Ensuring Dynamic Module Safety

Isolation: Modules are isolated from each other and the global scope, preventing accidental or malicious modification of other modules' state.
Integrity: Ensuring that the code being executed is the code that was intended, without tampering or modification.
Permissions: Modules operate within a specific permission context, limiting their access to sensitive resources.
Vulnerability Mitigation: Mechanisms to prevent or mitigate common vulnerabilities like Cross-Site Scripting (XSS) and arbitrary code execution.

JavaScript modules have revolutionized web development, offering a structured approach to code organization, reusability, and maintainability. While static modules loaded via `
