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 @jalayna

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• without: returns new array of only wanted items
• takeUntil: returns part of the array until callback returns a truthy value
• tail: recreates tail of given array onto new array
• middle: finds and returns middle of array
• map: create our own version of map
• letterPositions: finds index of letter
• head: return first element of an array
• findKeyByValue: returns key by it's value
• findKey: return the first key for which the callback returns a truthy value
• eqObjects: takes in two objects compares if identical. Only handle primitive types
• eqArrays: compares if two arrays are identical
• countOnly: counts items in array that repeat
• countLetters: counts how many times each letter appears in the string given
• assertObjectsEqual: takes in actual and expected as arguments and logs whether assertion passed or faild
• assertEqual: takes in actual and expected and logs if identical
• assertArraysEqual: takes two arrays and ensures they are equal and logs it
• tailTest: tests if tail function works
• middleTest: tests if middle function works
• headTest: tests if head function works
• eqArraysTest: tests if eqArray function works
• asserEqualTest: tests is assertEqual function works
• assertArraysEqualTest: tests if assertArraysEqual function works
