1:38 - What is a Standard Lib?

  • Still experimental
  • Built-in modules don't have to be downloaded because they ship with the browser
  • Not exposing built-in modules globally has a lot of advantages:
    • They won't add any overhead to starting up a new JavaScript runtime context (e.g. a new tab, worker, or service worker)
    • They won't consume any memory or CPU unless they're actually imported
    • They don't run the risk of naming collisions with other variables defined in your code

6:47 - Key Value Storage is the first one:
