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 @rhaelynlashmar/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head: a function to retrieve the first element in a given array
• tail: a function to retrieve all elements following the first
• middle: a function to retrieve the middle element of an array
• assertArraysEqual: a function to assert if 2 arrays compared are === from actual input to expected output
• assertEqual: a function to compare 2 primitive inputs and ascertain if actual input === expected output
• assertObjectsEqual: a function to assert if 2 objects compared are === from actual input to expected output
• countLetters: a function that takes in a sentence and returns the count of each of the letters in that sentence
• countOnly: a function that takes in a collection of items and return counts for a specific subset of those items
• eqArrays: a function that takes 2 arrays amd returns true or false, based on a perfect match
• eqObjects: a function that takes in 2 objects and returns true or false, based on a perfect match
• findKey: a function which takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue: a function which takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• letterPositions: a function which returns all the indices in the string where each character is found.
• takeUntil: a function thatn returns items in the array up to the point where the callback returns a truthy value.
• without: a function which will return a subset of a given array, removing unwanted elements.
• map: a function that creates a new array with the results of calling a provided function on every element in the array.
• flatten: a function which will take in an array containing elements including nested arrays of elements, and return a single condensed array.
