For Certain Operators, This Course Includes The Most Detailed Explanation Available Anywhere;

The rxjs of() operator returns an observable with values from the source observable. In brief, a pipeable operator is just a function that takes a source observable and returns an observable, for example: Operators are the bread and butter of rxjs.
