Just because functions are first class objects, there are closures, and higher order functions, does Javascript deserve to be called a Functional Programming language? The main thing I think it lacks is Pure Functions, and it doesn't 'feel' like other functional languages, like lisp (although thats not really a good reason for it not to be a functional langauge...)

Repeating my own answer to a similar question,




There's no accepted definition of
functional programming language.



If you define functional language as
the language that supports first class
functions and lambdas, then yes, JavaScript *is* a
functional language.



If you also consider the factors like
support for immutability, algebraic
data types, pattern matching, partial
application etc then no, JavaScript
*is not* a functional language.





I'd encourage you to read the
following related blog posts (and also
the comments below them):
