Is event-driven programming only possible with some programming languages?
Event-driven programming and reactive programming can be used with virtually any programming language and any programming paradigm. However, not all programming languages are equal in their ability to write event-driven code. Usually, the more low-level the programming language, the most difficult it is to write event-driven code in it. The term low-level is used here to describe the functionalities supported by the programming languages, not the fact that it is designed for system programming rather than applicative programming. A language with no support for closures, anonymous functions, and generators will lead to event-driven code that's hard to write, read, and maintain.
What are the differences between reactive programming and reactive systems?
Reactive programming is a way to structure...
