@tseclifford/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 @tseclifford/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(firstArray, secondArray): will log ✅ or 🛑 as to whether the two arrays are identical.
• assertEqual(actual, expected): will log "✅ Assertion Passed" or "🛑 Assertion Failed" when comparing actual and expected primitive data types.
• assertObjectsEqual(object1, object2): will log "✅ Assertion Passed" or "🛑 Assertion Failed" when comparing two objects.
• countLetters(str): will count the letters of a string and return an object containing the total count of each letter in string.
• countOnly(allItems, itemsToCount): will return a count of the items within a collection of items.
• eqArrays(firstArray, secondArray): will check if the first array equals the second array.
• eqObjects(object1, object2): will check if the first object equals the second object.
• findKeyByValue(obj, keyValue): will return the first key that contains a value, or undefined if there is no key.
• findKey(obj, callback): will return the first key for which the callback returns a truthy value, or undefined if no key is found.
• flatten(array): will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• head(array): will return the first item in the array.
• letterPosition(string): will return all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): will return a new array of elements modified by the callback function.
• middle(array): will return all the indices (zero-based positions) in the string where each character is found.
• tail(array): will return the "tail" of an array: everything except for the first item (head) of the provided array.
• takeUntil(array, callback): will return a "slice of the array with elements taken from the beginning until the callback returns a truthy value.
• without(array, itemsToRemove): will return a subset of a given array, removing unwanted elements.
