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 @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
