Monkey Patching shows the flexibility of JavaScript as well as some of its dangers

Monkey Patching is the capability in JavaScript to swap out a function in a JavaScript object with your own function. This can come in handy, but also be dangerous. One of JavaScript’s strengths is its ability to easily make changes to objects and modules. It also makes it fairly easy to introduce new bugs.

This kind of functionality can also be found in languages like Objective-C and Swift where developers can swap out the functionality of methods in their classes using a runtime feature called ‘Method Swizzling’.

To illustrate this functionality, we can create a object that has a simple add function.

class SimpleMathObject {

    add(a, b) {
        return a + b;
    }

}
