| * The opposite of `_.initial` this method gets all but the first element or |
| * first `n` elements of an array. If a callback function is provided elements |
| * at the beginning of the array are excluded from the result as long as the |
| * callback returns truey. The callback is bound to `thisArg` and invoked |
| * with three arguments; (value, index, array). |
| * |
| * If a property name is provided for `callback` the created "_.pluck" style |
| * callback will return the property value of the given element. |
| * |
| * If an object is provided for `callback` the created "_.where" style callback |
| * will return `true` for elements that have the properties of the given object, |
| * else `false`. |
| * |
| * @static |
| * @memberOf _ |
| * @alias drop, tail |
| * @category Arrays |
| * @param {Array} array The array to query. |
| * @param {Function|Object|number|string} [callback=1] The function called |
| * per element or the number of elements to exclude. If a property name or |
| * object is provided it will be used to create a "_.pluck" or "_.where" |
| * style callback, respectively. |
| * @param {*} [thisArg] The `this` binding of `callback`. |
| * @returns {Array} Returns a slice of `array`. |
| * @example |
| * |
| * _.rest([1, 2, 3]); |
| * // => [2, 3] |
| * |
| * _.rest([1, 2, 3], 2); |
| * // => [3] |
| * |
| * _.rest([1, 2, 3], function(num) { |
| * return num < 3; |
| * }); |
| * // => [3] |

| * var characters = [ |
| * { 'name': 'barney', 'blocked': true, 'employer': 'slate' }, |
| * { 'name': 'fred', 'blocked': false, 'employer': 'slate' }, |
| * { 'name': 'pebbles', 'blocked': true, 'employer': 'na' } |
| * ]; |
| * |
| * // using "_.pluck" callback shorthand |
| * _.pluck(_.rest(characters, 'blocked'), 'name'); |
| * // => ['fred', 'pebbles'] |
| * |
| * // using "_.where" callback shorthand |
| * _.rest(characters, { 'employer': 'slate' }); |
| * // => [{ 'name': 'pebbles', 'blocked': true, 'employer': 'na' }] |
