RxJS:

Reactive Programming

by Francisco Ramos

What is reactive programming?

• Programming with asynchronous streams.
• Creating a data stream of anything.
• Manipulate, combine, create, filter, map, and a long etc...

Why do we even need it?

• Web Apps have changed from static and sync to dynamic and async.
• Apps have evolved to be more real-time and real-time events comprise all sort of events.
• Reactive architectures (event-driven) are more manageable and scalable.

... but we already have:

• Callbacks
• Promises
• EventBus/PubSub
