The term "reactive programming" refers to a programming style based on handling "events" of all sorts. App developers are familiar with simple user interface events, such as mouse clicks, and know how to deal with them using their favorite programming language. But there are also other kinds of events an app may have to deal with, such as a state change of an object, an incoming message, the completion of an asynchronuous operation or an exception/error event.

Don't confuse a DOM collection with a JS array: Array functions, such as the
forEach looping method, cannot be applied to a DOM collection!
For instance, when you retrieve all rows of an HTML table element, you get an
HTMLCollection, which is an array-like object, but not an instance of
Array, and therefore the following code does not succeed because the
forEach is not defined for an
