Question

Hi and thanks for looking!

Background

I am building my first application in Node.JS and am replacing jQuery-based habits with native JavaScript.

For most items, this is trivial; however, I am finding that I really miss the elegance of jQuery’s $.each() abstraction and I would like to do something similar without relying on jQuery.

Unfortunately, the same code in JavaScript is a bit cumbersome:

myArray = ["item 1", "item 2", "item 3"];
for(i=0; i<myArray.length; i++) {
    myArray[i] = "Do Something Here".
};

What I would like to do is have something like this:

myArray = ["item 1", "item 2", "item 3"];
myArray.each(function(){
    //do stuff
});

Question

Is there already an extension method out there for accomplishing this? I can’t help but think I am re-inventing the wheel. If there isn’t anything out there, would an extension method be best?

Answer 1

You have forEach() in EcmaScript 5 : https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/forEach

But it’s not comptatible with IE < 8.

So you may need to use this lib to be supported by all browsers : https://github.com/kriskowal/es5-shim
