Fun things I’ve been learning lately about the modern ways to do things on the web:

• The Blob API!
  (For generating downloadable export files on demand.)
• async Promises!
  (For accepting an uploaded file and obtaining its text. Special guest star: Blob.text().)
• CSS Grid layout!
  (Because I should probably remake the whole layout with it someday.)

As always, MDN Web Docs has been invaluable for documentation and examples.

A cool feature is cooking!
