If we want a view of reactive programming from 50,000 above ground level, it can briefly be termed as:
When input x in any function changes, output y automatically updates in the corresponding response without the need to manually invoke it. In short, the sole purpose is to continuously respond to external inputs whenever prompted by output worlds.
Reactive programming is achieved through utilities such as map, filter, reduce, subscribe, unsubscribe, streams. Reactive programming focuses more on events and message-driven patterns rather than manually fiddling with huge implementation details.
Let's take a practical day-to-day example to understand reactive programming. We all have used Excel since the beginning of our IT lives. Now, let's say you write one formula based on a cell value. Now, whenever the cell value is changed...
