// When programming, there will certainly be times you will want to associate values to other values,
// that is building a dictionary.
// In TypeScript, a `Map<K, V>` exists (it seems it actually is the one defined in JavaScript ES6).
// However, at least in TypeScript 3.1.6, objects from this class are not very reliable:
// You will sometimes get errors such as "TypeError: map.get is not a function", at seemingly random times.
    
// A solution is to replace `Map<string, V>` by plain objects defined as `{ [key: string]: V }`.
// Another solution seems to be to replace them by `Record<string, V>`.

  We're splitting off the file extension in order to add "@2x"
  if the image is retina ready, else use a regular image with "data-no-retina".
  Image extension is assumed 3 characters. PNG, JPG, GIF (no JPEG).

Troubleshooting AWS unauthorized errors in lambda requests

This is mainly for node.js but might apply to other environments. Unsure.

If you are running a AWS Lambda function that calls another AWS service and getting an error about invalid tokens or other access denied errors, do this:

Check IAM

The role assigned to your lambda function will need permission to perform the actions. Check IAM and make sure the role has all the permissions.

If:

- you add and commit with the wrong email address in git, and
- your remote has a hook set up to prevent you from pushing with the bad address

Then you need to amend the author of your commit before push can succeed:

1. fix your email address in git config:

$ git config user.name "Your Name"
