A lotide library developed in Lighthouse Labs Weeks 1 - 2. Meant for learning purposes only.

Usage no npm install needed!

<script type="module">
  import chrischoi96Lotide from 'https://cdn.skypack.dev/@chrischoi96/lotide';



A mini clone of the Lodash library.


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.


Install it:

npm install @chrischoi96/lotide

Require it:

const _ = require('@chrischoi96/lotide');

Call it:

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