/** |
|
* Creates an object composed of keys generated from the results of running |
|
* each element of `collection` thru `iteratee`. The corresponding value of |
|
* each key is the last element responsible for generating the key. The |
|
* iteratee is invoked with one argument: (value). |

|
* @param {Array|Object} collection The collection to iterate over. |
|
* @param {Function} [iteratee=_.identity] The iteratee to transform keys. |
|
* @returns {Object} Returns the composed aggregate object. |
|
* @example |
|
* |
|
* var array = [ |
|
* { 'dir': 'left', 'code': 97 }, |
|
* { 'dir': 'right', 'code': 100 } |

* _.keyBy(array, function(o) { |

* return String.fromCharCode(o.code); |

* // => { 'a': { 'dir': 'left', 'code': 97 }, 'd': { 'dir': 'right', 'code': 100 } } |
|

|
* _.keyBy(array, 'dir'); |
|
* // => { 'left': { 'dir': 'left', 'code': 97 }, 'right': { 'dir': 'right', 'code': 100 } } |
