Code Reuse With Node.js

[fraserxu]

The first example: The "Function copy"

var objectA = {
    lorem: 'lorem ipsum'
};
var objectB = {};

// Direct copy of a string, but you get the idea
objectB.lorem = objectA.lorem;
console.log(objectB); // Will output: { lorem: 'lorem ipsum' }

I usually do this:

Object.keys(a).forEach(function(key) {
    b[key] = a[key];
})

Done!

About Object.defineProperties()

The __defineGetter__ method seems to have been deprecated. But I don't know why many people are still using it. See here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineGetter

And also I suggest to put some related post on it. Like:

• http://killdream.github.io/2011/10/09/understanding-javascript-oop.html

@makara ? Want to weight in that discussion. This goes live tonight 8:00 PM on Hacker News + Reddit + Google+...

Thanks.

• About the first example, it's same thing isn't it.
• About __defineGetter__, it works well in Node.js, plus you don't need to take care of other property attributes which you need to with Object.defineProperty.
• About the related posts:
  • Not sure what is the 1st.
  • 2nd is good, we can refer to it, but it's just some basics.
  • Underscore's mixin is not the same thing. It's for underscore itself.
  • The last is just a reference, but we can refer to it.

The next time send a Pull Request (really).

Any other link you would give as a resource @makara ?

No more additions.

Published. Didn't work well: I think mostly because of the title and the posting day (Thursday instead of Wednesday).
