Install it:

npm install @courtamos/lotide

Require it:

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

Call it:

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

• middle: function that takes an array and returns the middle element/s

• assertArraysEqual: function that takes two arrays and console.log an appropriate message to the console reflecting if the two arrays are equal

• assertEqual: function to help test code

• assertObjectsEqual: function that takes two objects and console.log an appropriate message to the console reflecting if the two objects are equal

• countLetters: function that takes a sentence and returns a count of each of the letters in that sentence

• countOnly: function that takes a collection of items and returns a count for a specific subset

• eqArrays: function that takes in two arrays and returns true or false based on a perfect match

• eqObjects: function that takes in two obejcts and returns true or false based on a perfect match

• findKey: function that takes an object and a callback, and scans the object to return the first key for which the callback returns a truthy value

• findKeyByValue: function that takes an object and a value, and scans the object to return the first key that contains the given value

• flatten: function that takes an array containing elements, including nested arrays of elements, and returns a flattened version of the array

• letterPositions: function that takes a string and returns all the indices in the string where each character is found

• map: function that takes an array and a callback, and returns a new array based on the results of the callback function

• takeUntil: function that takes an array and a callback, and returns a slice of the array with items taken from the beginning until a truthy value is found

• without: function that takes an array and a remove list, and returns a subset of a given array removing unwanted elements
