Enhance the current Angular function found in the angular/core package

I'm curious if there's a way to monkey patch an existing function within the angular/core package so that the modified function is always used instead of the original one. Just to clarify, I don't directly call this function myself; it's invoked by Angular itself.

More specifically, I want to alter this function without having to submit a pull request or fork Angular. For simplicity's sake, let's say I simply want to append console.log('changed') to the end of the function without changing anything else.

My recommendation is to avoid changing functions within a pre-existing package. Instead, you can either: 1) create your own function that encapsulates the original one, or 2) duplicate and paste the original function into your code, making modifications there.

When working with Angular, it is advised not to alter the internal functions as it may be unclear where Angular utilizes those functions internally. This can lead to challenges in managing changes within a team setting. Instead, if you need to customize functionality for your application, consider extending the class or implementing the interface based on your specific requirements.

One way to enhance an existing angular core class or interface is by importing it from the source module. However, altering or overriding a function exported from the source module is not possible.

You have the option to create a new class and export it. Inside this class, you can define a wrapper function that invokes the original angular function.

export class ExampleClass{

  // Define your wrapper function here
}

In pages where you wish to use your custom function instead of directly calling the angular function, import your class as demonstrated below:

import {ExampleClass} from <your ts file>

Subsequently, you are able to utilize your customized method within that page.
