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 @sam_maisha/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: takes in two arrays and console.log an appropriate message to the console.
• assertEqual: prints out a pass or fail message based on if actual value matches expected value
• assertObjectsEqual: take in two objects and prints an appropriate pass/fail message to the console
• countLetters: takes in a sentence (as a string) and then return a count of each of the letters in that sentence
• countOnly: returns an object containing counts of everything in the array provided it is in the input object
• eqArrays: takes in two arrays and returns true or false, based on a perfect match
• eqObjects: returns true if both objects have identical keys with identical values, otherwise returns false
• findKey: scans object and returns the first key for which the callback returns a truthy value
• findKeyByValue: takes in an object and a value. Function scans the object and returns the first key which contains the given value. If no key with that given value is found, function returns undefined
• flatten: takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array
• head: returns the first item in the array
• letterPositions: returns all the indices (zero-based positions) in the string where each character is found
• map: takes in two arguments - an array to map, and a callback funtion - function returns a new array based on the results of the callback function
• middle: takes in an array and return the middle-most element(s) of the given array
• tail: returns everything except for the first item of the provided array
• takeUntil: keeps collecting items from the input array until the callback provided returns a truthy value
• without: takes in a source array and itemsToRemove array, and will return a subset of a given array, removing unwanted elements
