@yuliiamatich/lotide v1.0.0

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 @yuliiamatich/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): compares two arrays by telling if they are equal or not.
• assertEqual(value1, value2): compares two values by telling if they match or not.
• assertObjectsEqual(object1, object2): takes in two objects and console.log an appropriate message to the console (true of false).
• countLetters(string): takes in a sentence (as a string) and then returns a count of each of the letters in that sentence
• countOnly(array, object): takes in a collection of items (array) and returns counts for a specific subset of those items(everything that the input object listed).
• eqArrays(array1, array2): takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): compares two objects and returns true or false, based on a perfect match.
• findKey(object, callback): scans the object and returns the first key for which the callback returns a truthy value. If no key is found - returns undefined.
• findKeyByValue(object, objectValue): searches for a key on an object where its value matches a given value.
• head(array): retrieves the first element from the array.
• letterPositions(string): returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): returns a new array based on the condition passed to the callback function.
• middle(array): returns the middle-most element(s) of the given array.
• tail(array): retreives every element of the array except the first element.
• takeUntil(array, callback): returns a slice of the array with elements taken from the beginning, keeps going until the callback returns a truthy value.
• without(array1, array2): returns a subset of a given array, removing unwanted elements.
