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 @sayantan2512/lotide

Require it:

const _ = require('@sayantan2512/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: it takes in two arrays and prints an appropriate message to the console.
• assertEqual: checks if both input and output have a perfect match.
• head: returns the element in 0th index of the given array.
• tail: returns the rest of the array after removing the 0th index element.
• middle: returns the middle element of an array.
• map: it will return a new array based on the results of the callback function.
• min: returns the lowest number in an array.
• sum: it take node arguments and returns thier sum.
• assertObjectsEqual: detects that two objects are equal.
• countLetters: returns a count of each of the letters in that sentence.
• countOnly: it takes in an array and an object & return an object containing counts of everything that the input object listed.
• eqArrays: it takes in two arrays and returns true or false, based on a perfect match.
• eqObjects: it takes in two objects and returns true or false, based on a perfect match.
• findKey: it takes in an object and a callback func and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue: it takes in an object and a value and returns the key for that value.
• flatten: it takes in an array containing elements including nested arrays of elements, and returns a "flattened" version of the array.
• letterPositions: returns all the indices (zero-based positions) in the string where each character is found.
• takeUntil: returns a "slice of the array with elements taken from the beginning."
• without: return a new array with only those elements from source that are not present in the itemsToRemove array.
