@paultaylor/lotide v1.0.2

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 @paultaylor/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertEqual): compares two simple data elements, returns true if identical, false if not
• function2(countLetters): from a string input, creates an object with the count of each occurrence of each letter in the string
• function3(countOnly): expects an array and an object. It will return an object containing counts of everything that the input object listed.
• function4(eqArrays): expects 2 array inputs, returns true if they are identical, false if not
• function5(eqObjects): expects two objects and returns true or false, based on a perfect match.
• function6(findKey): expects an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value. If no key is found, returns undefined.
• function7(findKeyByValue): expects 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, returns undefined.
• function8(flatten): reduces multi-layer arrays to a single flat array.
• function9(head): input an array - returns an array of only the first item
• function10(letterPositions): from a string input, creates an object with the index locations of each occurrence of each letter in the string
• function11(map): expects an array and a callback function. Returns a new array based on the results of the callback function.
• function12(middle): given an array input, returns the middle item(s) by index (i.e. returnArray1 of inputArray0, 1, 2 or returnArray1, 2 of inputArray0, 1, 2, 3)
• function13(reverse): returns a reversed version of an input string
• function14(tail): input an array - returns an array without the original array index 0. (chops off the first element)
• function15(takeUntil): input an array and a stop trigger. reads through the input array, builds a return array of all values until finding the stop trigger.
• function16(without): input 2 arrays. function returns the first array minus all matching element in the second array.
