Introduction to Observables
Explore the fundamentals of RxJS Observables within TypeScript to handle asynchronous event streams. Understand creating Observables, subscribing to event data, using transformation and combination operators, and managing errors to build reactive applications.
We'll cover the following...

One of the most intriguing, somewhat difficult, but fun parts of JavaScript programming is based around the handling of events. Whenever we issue an asynchronous call, we are essentially waiting for an event to occur that will trigger our callback processing. We generally have no control over how long an asynchronous call might take, especially if this call is to a server somewhere via an API call.
