Lodash lowerCaseKeys

Extend Lodash to take a value and recursively convert all keys to lowercase. This is intended for cleaning up data (usually from a third party) which has inconsistent or unpleasant key naming. Renaming of keys is done recursively (i.e. a 'deep' copy is made) and the input value is left unchanged.

_.lowerCaseKeys(value)

Arguments
value: The array or object value to have it's keys converted. Required.
If a simple value (string, number, etc) is provided it will be returned unchanged.

Returns
(object): An array or object with the keys converted to lowercase.

Example

var _ = require('lodash')
require('lodash-lowerCaseKeys')

_.lowerCaseKeys(
    [
        ['UNCHANGED 1', 'UNCHANGED2', 'THIS WILL BE NOT BE CHANGED'],
        {
            KEY1: 12,
