@daraakitoye/lotide v1.0.1

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 @daraakitoye/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arrOne, arrTwo): Takes in two arrays and logs an appropriate message to the console depending on whether or not they are a perfect match.

• assertEqaul(actual, expected): Compares the two values it takes in and print out a message telling if they match or not.

• assertObjectsEqual(actual, expected): which will take in two objects and logs an appropriate message to the console depending on whether or not they are a perfect match.

• countLetters(string): Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.

• countOnly(allItemsArr, itemsToCountObj): countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed.

• eqArrays(arrOne, arrTwo): Takes in two arrays and returns true or false, based on a perfect match.

• eqObjects(obj1, obj2): Will take in two objects and returns true or false, based on a perfect match.

• findKey(obj, callback): Takes in an object and a callback. It should 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(obj, value): Searches for a key on an object where its value matches a given value.

• flatten(array): Takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.

• head(array): A function which returns the first item in the array.

• letterPositions(string) : Returns all the indices (zero-based positions) in the string where each character is found.

• map(array, callback): Takes an array to map, a callback function, and will return a new array based on the results of the callback function.

• middle(array): Takes in an array and return the middle-most element(s) of the given array.

• tail(array): Returns the "tail" of an array: everything except for the first item of the provided array.

• takeUntil(array, callback): Will keep collecting items from a provided array until the callback provided returns a truthy value.

• without(sourceArr, unwantedElem): Returns a subset of a given array, removing unwanted elements.
