In this Hasty Treat, Scott and Wes discuss the Javascript standard library proposal — what it is, how it could influence dev, and what they’d like to see.

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:

• KV Storage: the Web’s First Built-in Module

8:36 - What do we want to see?

• Deep clone
  • Basically all of Lodash
• util.isDeepScrictEqual
• Async json.parse() / json.stringify
• UUID
• URL Lib for building and parsing URLs
• Missing Array Methods
  • Most of underscore JS
