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 @okenai/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertArraysEqual): function which compares the two arrays it takes in and print out a message telling us if they match or not.
• function2(assertEqual): function which compares the two values it takes in and print out a message telling us if they match or not.
• function3(assertObjetsEqual): function which compares the two objects it takes in and print out a message telling us if they match or not.
• function4(countLetters): function which takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• function5(countOnly): function which takes in a collection of items and return counts for a specific subset of those items.
• function6(eqArrays): function which takes in two arrays and returns true or false, based on a perfect match.
• function7(eqObjects): function which will take in two objects and returns true or false, based on a perfect match.
• function8(findKey): function which 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.
• function9(findKeyByValue): function which takes in an object and a 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.
• function10(head): function which returns the first item in the array
• function11(letterPositions): function which returns all the indices (zero-based positions) in the string where each character is found.
• function12(map): map array method prototype, a function which takes in array and return a value described by a second arguement a callback function.
• function13(middle): function which will take in an array and return the middle-most element(s) of the given array.
• function14(tail): function which returns the "tail" of an array: everything except for the first item (head) of the provided array.
• function15(takeUntil): function which will keep collecting items from a provided array until the callback provided returns a truthy value.
• function16(without): function which returns a subset of a given array, removing unwanted elements.
