Is JavaScript functional?

About this time, another important question that you should be asking: Is JS a functional language? Usually, when thinking about FP, the mentioned languages do not include JS, but do listless common options, such as Clojure, Erlang, Haskell, or Scala. However, there is no precise definition for FP languages or a precise set of features that such languages should include. The main point is that you can consider a language to be functional if it supports the common programming style associated with FP.
