[javascript] Node.js: for each … in not working

I wanted to use for each ... in with Node.js (v0.4.11).

I use it like this:

var conf = {
   index: {
      path: {
         first: "index.html",
         pattern: "index/{num}.html"
      },
      template: "index.tpl",
      limit: 8
   },
   feed: {
      path: "feed.xml",
      template: "atom.tpl",
      limit: 8
   }
}

for each (var index in conf) {
  console.log(index.path);
}

I get the following error:

        for each (var index in conf) {
     ^^^^

node.js:134
        throw e; // process.nextTick error, or 'error' event on first tick
        ^

Where is the mistake? for each ... in is supported since Javascript 1.6.

See MDN for information about the usage of for each ... in.

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

https://github.com/cscott/jsshaper implements a translator from JavaScript 1.8 to ECMAScript 5.1, which would allow you to use 'for each' in code running on webkit or node.

for those used to php:

//add this function
function foreach(arr, func){
  for(var i in arr){
    func(i, arr[i]);
  }
}

usage:

foreach(myArray, function(i, v){
  //run code here
});

similar to php version:

foreach(myArray as i=>v){
  //run code here
}

for (var i in conf) {
  val = conf[i];
  console.log(val.path);
}

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 > 0) {
            countElements.forEach(function(countElement){
                console.log(countElement);
            });
        }
