What's the difference between 'rxjs/operators' and 'rxjs/internal/operators'?

Question

In an Angular project, when I try to import things like Observable, or in this case, the switchMap operator, I have two options:

import { switchMap } from 'rxjs/operators';

or

import { switchMap } from 'rxjs/internal/operators';

What's the difference?

Answer 1

There is no difference.

import { switchMap } from 'rxjs/operators';

Is also loaded from the internal location, see operators/index.ts

I would suggest using the first one, if the rxjs maintainers change the internal project structure, it won't break your imports.
