Lotide

About

A mini clone of the lodash JavaScript library to practice creating various types of functions using JS. The Lotide project is a modular collection of functions that operate on data, namely Arrays and Objects.

Purpose

**BEWARE: This library was published for learning purposes. It is not intended for use in production. This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install@rorina/lotide

Require it:

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

Call it:

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

Documentation

The following functions currently implemented are listed alphabetically below :

• assertArraysEqual(...) : function which takes in two arrays and prints an appropriate message after comparing the two given arrays.

• assertEqual(...) : custom assertion function which compares two values and prints out a colorful message to console in both success and failure.Emojis are used to add visuals and color to the assertion output.

• assertObjectsEqual(...) : takes in two objects to compare and logs an approprate assertion emoji included messages to the console.

• countLetters(...) : takes in a sentence as a string and then returns a count of each of the letters in the given sentence.

• countOnly(...) : takes in a collection of items and returns a specific subset of those items(in this case limited to strings).

• eqArrays(...) : takes in 2 arrays and returns true if the arrays are equal and false otherwise.

• eqObjects(...) : takes in 2 objects and return true if they are equal and flase otherwise.

• findKey(...) : takes in an object and a callback and then returns the first key that meets the criteria specified in callback

• findKeyByValue(...) : takes in an object and a value as argument and returns the first key that corresponds to that value.

• flatten(...) : takes in an array that contains elements including nested array of elements and then returns a flatttened version of the input array.

• head(...) : takes in an array as argument and returns the first element in the given array.

• letterPositions(...) : function takes in a string input and returns all indices of letter positons in the given string.

• map(...) : takes in an array and a callback and returns a new array based in the results of the callback on each item in the array.

• middle(...) : takes in an array and returns middle most element of the array

• tail(...) : takes in an array as argument and returns everything except the first element of the array.

• takeUntil(...) : takes in an array and callback and retuns a slice of the array based on the results of the callback on each item in the array.

• without(...) : takes in a source array and an itemsToRemove arrays and returns only the items from the source array that are not in the itemsToRemove array.
