Follow-up to Top-level await is a footgun – maybe read that first
Here are some things I believe to be true:
- Static module syntax is beneficial in lots of ways – code is easier to write (you get better linting etc) and easier to optimise (tree-shaking and other things that are only really possible with static syntax), and most importantly, faster to load (it's trivial for a module loader to load multiple dependencies concurrently when they're declared with a static syntax – not so with imperative statements like
require(...)
orawait import(...)
). - App startup time is perhaps when performance is most critical. (You already know this, I don't need to cite the studies.)
- If you're in favour of constructs that jeopardise app startup time, you are anti-user. Top-level
await
is such a construct.
