The Function Constructor is a JavaScript feature that allows developers to create new functions dynamically by passing a string of code as an argument. While this can be useful for generating functions at runtime, it also introduces significant security risks. Attackers can exploit the Function Constructor to execute arbitrary code, leading to vulnerabilities such as code injection. Because the code is parsed and executed at runtime, it can bypass many static security checks. For this reason, its use is generally discouraged in secure coding practices, especially when handling untrusted input. Developers are advised to use safer alternatives whenever possible.
