javascript - Flatten object to array?

Question

I'm using an object as a hash table. I'd like to quickly print out its contents (for alert() for instance). Is there anything built in to convert a hash into arrays of (key, value) pairs?

Answer 1

Since you want to alert it out I assume it's not for your production version, and that old browser compatibility is not an issue.

If this is the case, then you can do this:

var myHash = ......
alert(Object.keys(myHash).map(function(key) { return [key, myHash[key]]; }));
