On the current typescript / anti-typescript internet drama I saw someone mention javascript without a build step.

Do you think we're already there?

Last time I attempted it:

• there were too many libraries I couldn't import
• JSX (using babel) had a warning saying you shouldn't do it in the browser for production
• there was some advice against not using a bundler, because several requests for different .js files is slower and bigger than a bundled package
