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 (dinopranjic) as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @dinopranjic/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): Takes in a string and returns an object containing all the letters in the string and how many times they occur.

• countOnly(allItems, itemsToRemove): takes in an array of items and an object listing items as true or false. Returns a new object containing all the items listed as true in the array and how many times they occur.

• eqArrays(firstArray, secondArray): takes in two arrays and returns true if they are the same or false if they are not the same.

• eqObjects(object1, object2): takes in two objects and returns true if they are the same or false if they are not the same.

• findKey(object, callback): takes in an object and a callback function. Returns a key according to the callback.

• findKeyByValue(object, value): takes in an object and a value. Returns a key with a value that matches the value input.

• flatten(array): takes in a two-dimensional array and returns a 'flattened' one-dimensional array.

• head(array): takes in an array and returns a new array containing the 'head' or first element.

• letterPositions(string): takes in a string and returns the index positions of each letter.

• map(array, callback): takes in an array and a callback function. Returns new modified array according to callback.

• middle(array): takes in an array. Returns a new array containing the middle element(s) of the array.

• tail(array): takes in an array. Returns a new array containing the 'tail' or every element but the first element.

• takeUntil(array, callback): takes in an array and callback function. Returns a new array containing elements up to, but not including, the first element to satisfy the callback function.

• without(source, itemsToRemove): takes in two arrays. Returns a new modified array with elements of the source array that did not match elments of the second array.

• assertEqual(actual, expected): takes in two primitive data types and console logs whether they are the same or not.

• assertArraysEqual(array1, array2): takes in two arrays and console logs whether they are the same or not.

• assertObjectsEqual(object1, object2): takes in two objects and console logs whether they are the same or not.
