Install it:

npm install @justin-moretto/lotide

const _ = require('@justin-moretto/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): takes an array and returns the 0 index
• tail(array): takes an array and returns it minus the 0 index
• middle(array): returns one middle element of an array (or two elements, if array.length is even)
• assertArraysEqual(actual, expected): compares two arrays and returns a bool
• assertEqual(actual, expected): compares two primitive data types and returns a bool
• assertObjectsEqual(actual, expected)): compares two objects and returns a bool
• countLetters(string): counts how many times each letter occurs in a string, returns an object
• countOnly(allItems, ItemstoCount): takes an array and an object; takes in a collection of items and return counts for a specific subset of those items; returns an object
• eqArrays(array1, array2): takes in two arrays and returns true or false, based on a perfect match
• eqObjects(): description
• findKey(): description
• findKeyByValue(object, value): search for a key on an object with given value
• flatten(): Given an array with other arrays inside, flattens it into a single-level array.
• letterPositions(string): return all indices in a string where each character is found; returns object
• takeUntil(): description
• without(): return a subset of a given array, removing unwanted elements.
• map(array, callback): return a new array based on the results of the callback function.
