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 @handsomepeasant/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(): returns the first element of an array
• tail(): returns all elements of an array except the first
• middle(): returns the middle element(s) of an array
• assertEqual(): compares two inputs and prints pass or fail message
• assertArraysEqual(): checks if two arrays are identical and prints a pass or fail message
• assertObjectsEqual(): checks if two objects are identical and prints pass or fail
• eqArrays(): function used by assertArraysEqual() to check values of arrays
• eqObjects(): function used by assertObjectsEqual() to check values of objects
• countLetters(): returns an object where each key-value pair is a letter that appears in the passed-in string & how many times it appears
• countOnly(): receives an array and an object that determines which items in the array will be counted
• findKey(): receives an object and a callback value, scans the object and returns the first key for which the callback returns a truthy value
• findKeyByValue(): simplified version of findKey()
• letterPositions(): returns all indices where each character in a string is found
• takeUntil(): returns items from a passed-in array until the specified callback returns a truthy value
• without(): takes in two arrays and returns a new array that does not include any items included in itemsToRemove
