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 Kevin Cogen as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @kevincogen/lotide

Require it:

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

Call it:

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

• assertEqual(...): Asserts strict equality between two inputs
• assertObjectsEqual(...): Assets equalit between two Objects
• countLetters(...): counts Letters in a given input and outputs Object that lists each Letter and Letter Count
• countOnly(...): takes in a collection of items and return counts for a specific subset of those items.
• eqArrays(...): compares two arrays
• eqObjects(...): compares two objects
• findKey(...): scans an object and returns first key which contains a value that returns true with callback function
• findKeyByValue(...): scans an object and returns the first key which contains a given value
• flatten(...): take in Array, including nested Array, and return a flattened Array
• head(...): take in Array, return array with only first item.
• letterPositions(...): takes in a string, converts to an array and returns an object that lists each index location of each letter used.
• map(...): takes in array to map and callback function - returns a new array based on results of callback function
• tail(...): takes in an array and returns a new array with first element removed
• middle(...): takes in an array and returns a new array with only the middle most element(s)
