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 @divyajagadish/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head:Returns the first element in an Array
• tail:Returns the tail of an array
• middle:Returns the middle portion of an Array
• assertArraysEqual: Assert arrays are Equal
• assertEqual :compare two values and assert Equal
• assertObjectsEqual : Asserts whether the Object are Equal or not.
• countLetters: Take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly : countOnly needs to return a proper report on all the strings found in the input array, and their respective counts only when it meets the truthy condition.
• eqArrays:Check whether arrays are Equal
• eqObjects: Check whether Objects are Equal
• findKey :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.
• findKeyByValue : Returns the key of a particular Key Value pair.
• flatten: Takes an array containing elements including nested arrays of elements, and return a "flattened" version of the array
• letterPositions: return all the indices (zero-based positions) in the string where each character is found.
• map: map function will return a new array based on the results of the callback function.
• takeUntil: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:Returns an array without the specified element.
