The list of requirements for frontend work keeps increasing. Websites that load quickly on shaky connections, render perfectly on mobile devices, and respond with lightning speed to user input are expected. All of these tasks require dealing with a high number of events from disparate sources, be it your Customer Relationship Management (CRM), late-breaking news, or just a chat room.

Observables is a new way of thinking about managing these events, even when they may occur sometime in the future.

In this course, you’ll learn how to delegate both the calls and control flow to RxJS, allowing you to focus on the rest of your application.

RxJS compartmentalizes eventing flows, encapsulating each action in a single function, providing many helper operators that keep an internal state, allowing you to outsource your state worries to the library.

By the end of this course, you will be able to build bigger, faster, and less-buggy applications for your users.

# RxJS built-in interval component

In the [previous lesson](https://www.educative.io/courses/reactive-websites-rxjs/running-a-timer), we wrote all of the code of the interval by ourselves. That was a lot of information in just a few lines
of code. There were a lot of new concepts, and it might get tedious writing
this every time we want an interval. 

Fortunately, all of this work has already
been implemented in the *Rx* library in the form of a creation operator `interval()`:



Let's see the built-in interval() function in RxJS and run it by using a subscribe call.
