/**
 * Jest Conversion script
 * This script isn't the cleanest, and uses two different methods for performing global replaces... but it gets the job done.
 * We switched from using the `replace` method to the `advancedReplace` about 70% of the way through, and couldn't go and retrofit
 * `advancedReplace` everywhere with 100% confidence. However, should you use this script as a base for your own migration,
 * I would definitely suggest using `advancedReplace`, which uses the node-replace library.

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

  passphrase = (new TextEncoder()).encode(passphrase);
  let digest = await crypto.subtle.digest({ name: 'SHA-256' }, passphrase);

    'raw',
