@sshruti14/lotide v1.0.1

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 @sshruti14/lotide

Require it:

const _ = require('@sshruti14/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(): Takes in two arrays and prints an appropriate message to the console telling us if they match or not.
• assertEqual(): The function compares the two values it takes in and prints out a message telling us if they match or not.
• assertObjectsEqual(): Take in two objects and prints an appropriate message to the console telling us if they match or not.
• countLetters(): returns an object where each unique character encountered is a property of the object and the value for that property/key should be the number of occurrences for that character.
• countOnly(): Takes in a collection of items and returns counts for a specific subset of those items.
• eqArrays(): Takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(): Takes in two objects and returns true or false, based on a perfect match.
• 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(): Takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• head(): returns the first item in an array.
• letterPositions(): returns all the indices (zero-based positions) in the string where each character is found.
• map(): returns a new array based on the results of the callback function.
• middle(): Takes in an array and return the middle-most element(s) of the given array.
• tail(): returns the "tail" of an array: everything except for the first item (head) of the provided array.
• takeUntil(): returns 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 a subset of a given array, removing unwanted elements.
