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 @irt.21/lotide

Require it:

const _ = require('@irt.21/lotide');

Call it:

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