const _ = require('@rhurtis/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): Takes an array input. Returns a single element array with the first element of the input array.
• tail(...): Takes an input array. Returns an array with the same elements except for the first element.
• middle(...): Will take in an array and return the middle-most element(s) of the given array.
• countLetters(...): Will take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• findKey(...): the function findKey will take in an object and a callback. It will scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined.
• findKeyByValue(...): Will take in an object and a callback. It will scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined.
• eqArrays(...): Takes in two arrays and returns true or false, based on a perfect match.
• countOnly(...): Given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqObjects(...): Takes in two objects and returns true or false, based on a perfect match.
• map(...): A homemade method that creates a new array populated with the results of calling a provided function on every element in the calling array.
• takeUntil(...): Will keep collecting items from a provided array until the callback provided returns a truthy value.
• without(...): Will return a subset of a given array, removing unwanted elements.
• letterPositions(...): Will return all the indices (zero-based positions) in the string where each character is found.
• assertArraysEqual(...): Tells whether or not two arrays are equal.
• assertEqual(...): States whether or not two non array inputs are equal.
• assertObjectsEqual(...): States whether or not two objects are equal.
