_.tail(array) source npm package Gets all but the first element of array. Since 4.0.0 Arguments array (Array): The array to query. Returns (Array): Returns the slice of array. Example _.tail([1, 2, 3]); // => [2, 3]

_.sumBy(array, [iteratee=_.identity]) source npm package This method is like _.sum except that it accepts iteratee which is invoked for each element in array to generate the value to be summed.
