Web worker example

This repo is an example of a web worker in action. The use case is a JPEG fetcher which transforms the response into a blob, then into an ArrayBuffer, then the EXIF data is extracted. There are two states denoted by two tags:

1. without-worker, which does all this work on the main thread.
2. with-worker, which moves the fetching, EXIF extraction, and markup construction into a web worker.

To use this repo, clone, npm install, and then spin up the local server via npm start. Once the server is started, it will be available at http://localhost:8080.
