In lodash, what is the opposite of `pairs()`?

Question

I cant't see it in the docs - http://lodash.com/docs - please help me:

What is the opposite of _.pairs()? There must be one - I just cant' see where!

The goal is to produce key/value pairs from an array of the form [['key1':'value1'], ['key2':'value2'], ...]

Not that I really need it a lib for that: I just like to re-use things..

I think you're looking for _.object/_.zipObject.

http://lodash.com/docs#zipObject

"use strict";  var obj, pairs, objResult;  obj = {     key1: "value1",     key2: "value2" };  pairs = _.pairs(obj); objResult = _.object(pairs);  // The original object. console.log(obj); // The object as an array of arrays. console.log(pairs); // The array of arrays converted back to the original object. console.log(objResult);
