Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(arr): returns 1 for 1, 2, 3.
• tail(arr): returns 2, 3 for 1, 2, 3.
• middle(arr): returns [] for 1 or 1, 2; 2 for 1, 2, 3; 2, 3 for

•              [1, 2, 3, 4].

• assertArraysEqual(actual, expected): test function for eqArrays.
• assertEqual(actual, expected): test function for functions with primitive

•                              values as output.

• assertObjectsEqual(actual, expected): test function for eqObject.
• countLetters(str): returns the count of each letter in the string.
• countOnly(allItems, itemsToCount): returns the count of item(s) in allItems,

•                                  specified in itemsToCount. Returns 

•                                  unidentified if item not specified.

• eqArrays(arr1, arr2): compares two arrays and return true or false.
• eqObject(obj1, obj2): compares two objects and return true or false.
• findKey(obj, callback): returns key based on the condition specified by

•                       the callback function.

• findKeyByValue(obj, value): returns key of input value.
• letterPositions(str): returns the indices of each letter in the string.
• map(array, callback): returns a new array with results from the callback on

•                     every element in the calling array.

• takeUntil(array, callback): returns a new array with values taken

•                           incrementally from the calling array until

•                           condition specified by the callback is met.

• without(source, itemsToRemove): returns a new array with all elements from

•                               the source input expect element specified by

•                               itemsToRemove.
