Monkey Patching (Node.js)

Monkey patching is a technique that involves modifying or extending existing code at runtime by replacing functions, methods, or modules with instrumented versions. This approach intercepts function calls and adds observability without requiring changes to the original source code.

Languages: This technique is commonly used in dynamic languages like JavaScript (Node.js), Python, Ruby, and other interpreted languages that support runtime modification of functions and modules.
