How do I get the name of an object key in a Javascript for...in loop?

Question

I can iterate over an object like this:

var obj = {name: "Fred"}

for(var value in obj) {
    // Key should be "name"
    console.log(key + ": " + value);
}

How can I find out what key is? Is this possible at all? Any help would be appreciated.

Yeah. If you are unfamiliar with a certain construct, such as `for...in`, read the docs first: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in . I mean, how did you even decide to use it if you don't know how it works :P ;) — Felix Kling, Nov 10 '15 at 18:11
