    Build an Event Combo Observable with RxJS

    rxjsRxJS
    >=6.5.3

    After another pat on the back from our manager, we get a notification that a new task has been assigned to us: “While most users find it useful, some have asked if they can disable the spinner. Add a feature that turns off the spinner functionality once a certain combination of keys has been pressed within a time period”. So in this lesson, we will look at building an observable factory, that can be initialized with a certain list of key codes, and will fire whenever that key combo gets pressed quickly, within a 5 second window. We will be introducing the fromEvent, concat and takeWhile operators.
