This might be an old qustion  but just to keep things updated  there is a forEach method in javascript that works with NodeJS  Here s the link from the docs  And an example        count   countElements length          if  count  gt  0                countElements forEach function countElement                   console log countElement

There s no for each in in the version of ECMAScript supported by Node js  only supported by firefox currently    The important thing to note is that JavaScript versions are only relevant to Gecko  Firefox s engine  and Rhino  which is always a few versions behind    Node uses V8 which follows ECMAScript specifications

Unfortunately node does not support for each     in  even though it is specified in JavaScript 1 6  Chrome uses the same JavaScript engine and is reported as having a similar shortcoming   You ll have to settle for array forEach function item       etc etc         EDIT  From Google s official V8 website      V8 implements ECMAScript as specified in ECMA-262    On the same MDN website where it says that for each    in is in JavaScript 1 6  it says that it is not in any ECMA version - hence  presumably  its absence from Node
