Hello All, I have been a great fan of the evolution of JavaScript in the recent past. The language is steadily closing the gap to ideal functional paradigm. One of the things that I have liked the most about languages like Erlang/Elixir/Haskell is their ability to define functions with same name and different airty. The decision of invoking the correct function-argument pattern is dependent on the invocation of the function. Implicit pattern matching in aforementioned languages helps avoid costly cognitive loads introduced by explicit if/else based pattern of logic flow branching.
The greatest power of the pattern matching which amazed me was, dropping the whole of looping construct, altogether. Elixir/Erlang have no LOOPS. Stack based recursive calls combined with JavaScript's closures suddenly strikes me as a very powerful programming model that not only increases readability of code but also promotes immutability of the data structures in use. The loops would continue to exist but more modern codes can be written leveraging the recursive model of JavaScript. With de-structuring of arrays & objects already in place in JavaScript, pattern-matching of functions can fit right in perfectly, thereby taking JavaScript another step closer to ideal functional programming model. Looking forward to your response. Thanks & Regards, Bishwendu.
