Dynamically sets a script's src attribute to load external code at runtime.

Creates functions from strings, similar to eval(), often used to hide malicious code.

Injects and executes scripts in web pages programmatically.

Uses eval() to execute dynamic code — a common vector for code injection.

Creates a function from a string (new Function()), similar to eval().

Object.defineProperty() called on window — can intercept and override built-in browser APIs.
