# Introduction

## Overview

The **xAPI.js Wrapper Library** is a strongly typed JavaScript library for enabling learning content and learning systems to speak to each other. It is a complete implementation and fully compliant against the [xAPI Specification](https://github.com/adlnet/xAPI-Spec) (v1.0.0 - v1.0.3).

For an example implementation of this library, you can find the [xAPI Wrapper Demo](https://github.com/xapijs/xapi-demo) source on GitHub.
