Lotide
A mini clone of the Lodash library.
Purpose
BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.
This project was created and published by me as part of my learnings at Lighthouse Labs.

Install it:
npm install @icornell/lotide
Require it:
const _ = require('@icornell/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected)
: uses eqArrays to check if two arrays are equal and prints out if they are equal or not -
assertEqual(actual, expected)
: checks if two values are equal -
assertObjectsEqual(actual, expected)
: uses eqObjects to check if two objects are equal and prints out if the assertion passed or failed -
countLetters(sentence)
: counts all the letters in a given string or sentence -
countOnly(allItems, itemsToCount)
: returns an object containing counts of everything in a string that the input object listed -
eqArrays(array1, array2)
: takes two arrays and returns true or false, dependant on a perfect match -
eqObjects(object1, object2)
: takes two objects and compares them to see if they are equal -
findKey(obj, callback)
: returns the first key of a given object that matches the callback -
findKeyByValue(object, value)
: finds the first key in a given object which matches the given value -
flatten(arr)
: takes nested arrays and flattens them into one single-level array -
head(arr)
: returns the first element, or head, of an array -
letterPositions.js(sentence)
: returns an object where the keys are the letters in a given sentence and the values the index positions where they appear -
map(array, callback)
: returns a new array based on the results of the callback function. -
middle(arr)
: returns the middle element(s) of an array - one or two, depending on if the array is even or odd -
tail(arr)
: returns the end elements, or tail, of an array (all but the head) -
takeUntil(array, callback)
: returns a slice of the array with elements taken from the beginning until the callback returns a truthy value -
without(source, itemsToRemove)
: returns a new array after having removed the given items in itemsToRemove
