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.

Usage

Install it:

npm install @kelsey-griffin/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the head of the array [1, 2, 3] => [1]
• tail(array): returns the tail of the array [1, 2, 3] => [2, 3]
• middle(array): returns the middle of the array (if even returns the two middle elements) [1, 2, 3, 4] => [2, 3]
• assertEqual(a, b): returns a boolean describing if two items are equal (not optimized for objects or arrays)
• assertObjectsEqual(obj1, obj2): returns a boolean describing if two arrays are equal
• assertArraysEqual:returns a boolean describing if two objects are equal
• countLetters("phrase"): returns an object containing the number of occurences of each letter in a phrase
• countOnly(fullList, shortList): given an object with a shortlist of items (listed true or false), function will return an object with the number of occurrences of each item that is true
• eqArrays(arr1, arr2): returns a boolean describing if two arrays are equal
• eqObjects(obj1, obj2): returns a boolean describing if two objects are equal
• findKey(obj, callback): returns the key from given object that matches callback function's requirements
• findKeyByValue(obj, value): returns the key matching a given value in an object
• letterPositions("phrase"): returns an array of the positions of each letter in a given phrase
• map(array, callback): returns a new array each element mutated according to the callback function
• flatten(array): flattens nested arrays into one array
• takeUntil(array, callback): returns each element of the array until the element meets callback function
• without(array, elementToRemove): returns an array with specified element removed
• recursive_eqArrays(array1, array2): returns a boolean describing if two arrays are equal (but with recursive code)
• recursive_eqObjects(obj1, obj2): returns a boolean describing if two objects are equal (but with recursive code)
