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 @tmackinnon/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(): returns the first item in the given array
• tail(): takes in an arrat and returns everything except the first item in it
• middle(): takes in an array and returns the middle-most element(s) of the given array, if array is one or two elements, returns empty array
• assertArraysEqual(): takes in two arrays and console.logs 'passed' if they are equal and 'failed' if they are not
• assertEqual(): take in two values and console.logs 'passed' if they are equal and 'failed' if they are not
• assertObjectsEqual(): takes in two objects and console.logs 'passed' if they are equal and 'failed' if they are not
• countLetters(): takes in a sentence (as a string) then returns a count of each of the letters in that sentence
• countOnly(): takes in a collection of items and returns the counts for a specific subset of those items
• eqArrays(): compares two arrays for a perfect match
• eqObjects(): takes in two objects and returns true or false, based on if they are a match
• findKey(): takes in an object and a callback, will 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(): takes in an object & value, scans the object and returns the first key which contains the given value. If no key with that given value is found, then it should return undefined
• flatten(): takes in an array containing elements (including nested arrays), and returns a "flattened" version of the array
• letterPosition(): returns all the indices in the string where each character is found
• map(): returns a new array based on the results of the callback function
• takeUntil(): collects items from a provided array until the callback provided returns a truthy value
• without(): returns a subset of a given array, removing unwanted elements
