Parses basic LISP statements and generates AST (as would be from http://esprima.org/demo/parse.html) which is then turned into JS using escodegen (https://github.com/estools/escodegen) and saved into an out.js file. Run in nodejs.

Modifications :
'define' keyword is to be written as 'const',
'lambda' keyword is to be written as the arrow operator, '=>'.

Supports: simple arithmetic with 2 or more paramters
math operations such as max, min
conditionals : if statements variable declarations and working with them
immediately invoked function expressions function recursion

Input examples :
(+ 5 5)
(const a 10)
(if (< 10 20) (+ 5 5) (+ 5 5 5 5))
(const fact (=> (n) (if (<= n 1) 1 (* n fact (- n 1)))))
((=> (a) (* a a)) 5)
((=> (a b c) (+ a b c)) 1 2 3)
