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, Hope! as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @hopevaughn/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual.js: Colourful replacement for the assert method.
• head.js: Returns the 0 index of an array and tests it for equality.
• tail.js: Returns a new array from the index 1 of a given array and tests it for equality.
• eqArrays.js: Takes in two arrays and returns true or false, based on a perfect match.
• assertArraysEqual.js: Takes in two arrays and will console.log and appropriate message to the console.
• without.js: Returns a subset of a given array, removing unwanted elements.
• flatten.js: takes in an array containing elements including nested arrays of elements, and returns a 'flattened' version of the array.
• middle.js: Takes in an array and returns the middle-most element(s) of the given array.
• countOnly.js: Takes an array and an object. It will return an object containing counts of everything that input object lists.
• countLetters.js: Takes in a sentence (as a tring) and then returns a count of each of the letters in that sentence.
• letterPositions.js: Returns all the indices (sero based positions) in the string where each charater is found.
• findKeyByValue.js: Takes in an object and a value then returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• eqObjects.js: Takes in twi objects and returns true or false, based on a perfect match.
• assertObjectsEqual.js: Take in two objects and will console.log an appropriate message to the console.
• map.js: Returns a new array based in the results of the callback function.
• takeUntil.js: Collects items from a provded array untill the callback provided returns a truthy value.
• findKey.js: Takes in an object and a callback then scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
