Underscore.js - Map Array of key/value pairs to an Object - One liner

rated 0 times [ 187] [ 7] / answers: 1 / hits: 63375 / 11 Years ago, tue, july 23, 2013, 12:00:00

I've been going through the underscore docs but I can't seem to find a method (or nested method call) to do the following transformation:

Let's say I have the following Javascript array:

 [{ name : sEcho, value : 1},{ name : iColumns, value : 12}, ... ]

And I need to transform it into the following object:

 {

      sEcho: 1,

      iColumns: 12,

      ...

 }

I'm using underscore.js for a reason so it must be a one liner.

Since nobody has posted this as an answer, I'm posting it because I think it is better than Jan's answer. It's shorter, and cleaner without the inline function.

_.object(_.pluck(data, 'name'), _.pluck(data, 'value'));
