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

Documentation

The following functions are currently implemented:

• head(...): retrieves the first element from the array
• tail(...): every element except the head (first element) of the array
• middle(...): return the middle-most element(s) of the given array
• assertArraysEqual(...): asserts equalities between two arrays
• assertEqual(...): asserts equalities between two values
• assertObjectsEqual(...): asserts equalities between two objects
• countLetters(...): taked in a sentence (as a string) and then return a count of each of the letters in that sentence
• countOnly(...): takes in a collection of items and return counts for a specific subset of those items
• eqArrays(...): compare two arrays for a perfect match
• eqObjects(...): takes in two objects and returns true or false, based on a perfect match
• findKey(...): takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue(...): search for a key on an object where its value matches a given value
• letterPositions(...): returns all the indices (zero-based positions) in the string where each character is found
• map(...): return a new array based on the results of the callback function
• takeUntil(...): keeps collecting items from a provided array until the callback provided returns a truthy value
• without(...): returns a subset of a given array, removing unwanted elements
