@lucky-kim/lotide v1.0.1

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 @lucky-kim/lotide

Require it:

const _ = require('@lucky-kim/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(...): This function returns series of success / failure messages printed to the console, letting us know if our functions are behaving as expected.

• head(...): This function is used to retrieve the first element from the array.

• tail(...): This function returns the tail of an array. It is meant to be every element except the head (first element) of the array.

• middle(...): This function returns an array with only the middle element(s) of the provided array. This means that the length of the returned elements could vary.

• eqArrays(...): This function can compare two arrays for a perfect match. except do not return true for nested arrays or arrays of objects that are identical

• eqArraysRecursive(...): This function can compare two arrays for a perfect match. Including return true for nested arrays or arrays of objects that are identical

• assertArraysEqual(...): This function will take in two arrays and console.log an appropriate message to the console to compare if the arrays are equal

• without(...): This function returns a subset of a given array, removing unwanted elements.

• flatten(...): Given an array with other arrays inside, it can flatten it into a single-level array.

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

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

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

• findKeyByValue(...): This function takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.

• eqObjects(...): This function takes in two objects and returns true or false, based on a perfect match.

• assertObjectsEqual(...): THis functions takes in two objects and console.log an appropriate message to the console.

• map(...): This function will return a new array based on the results of the callback function.

• takeUntil(...): This function will keep collecting items from a provided array until the callback provided returns a truthy value.

• findKey(...): This function 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.

• eqObjectsRecursive(...): This function takes in two objects and returns true or false, based on a perfect match. Including subObjects.
