Mastering Functional Programming

Use Case - A Parallel Web Crawler

In the previous chapter, we discussed the actors model and a framework that you can use to program with actors. However, the actor model is a paradigm just like functional programming. In principle, if you know the actors model from one language, you can use it in another language even if it doesn't have a framework that supports the actor model. This is because an actor model is an approach to reasoning about parallel computations, not some language-specific set of tools.

This state of things, just like functional programming, has its own benefits and drawbacks. The benefit is that you are not language-dependent if you depend on concepts. Once you know a concept, you can come to any programming language ...
