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 @kevchew/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Compares two arrays to see if they are equal and will print an assertion message accordingly.
• assertEqual(...): Compares two values to see if they are equal and will print an assertion message accordingly.
• assertObjectsEqual(...): Compares two objects to see if they are equal and will print an assertion message accordingly.
• countLetters(...): will count the number of letters in a given string.
• countOnly(...): Takes two objects. First will be an object of items and second will be the items that need to be counted.
• eqArrays(...): Will compare to two arrays to see if its values are equal.
• eqObjects(...): Will compare two obecjts to see if its key value pairs are equal.
• findKey(...): Will take an object and identify the first instance of that value and return its key.
• findKeyByValue(...): Will identify the input value's corresponding key.
• flatten(...): Takes in an array that may contain nested arrays of elements and join into one final sorted array
• head(...): Takes the first element of an array
• letterPositions(...): Returns an object of each letter and its positions(in key value pairs) of the inputted string.
• map(...): Will iterate over an array and apply a specific function to each items of the array.
• middle(...): Will return the middle elements of an array.
• tail: Returns everything but the first element of the array.
• takeUntil(...): Will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without(...): Takes two arrays. First an array of elements, Second an array of elements to take out. Returns a new array with only elements that are taken out remaining.
