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 @abellozo/lotide

Require it:

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

Call it:

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

• eqObjects(...): compares two objects
• findKey(...): scans the object and returns the first key for which the callback returns a truthy value
• findKeyByValue(...): scans the object and returns the first key which contains the given value
• flatten(...): 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
