oh no
"doesn't block loading" is contingent. If you structure your app to depend on the script, it'll still "block" even of the work is on a different thread.

True. With ScriptStreamingOnPreload (which we hope to ship in Chrome 75), this becomes less likely though. In many cases we complete parse + compile by the time the HTML parser sees the starting <script> tag, and we can just start executing right away.

Yes, and even if it's not ready, that's (mostly) due to network rather than parse. It's valuable to expose and to analyse, but as "download time" rather than "parse time" so that devs have a better idea of what to optimise (e.g. use brotli, invest in CDNs, etc.)

Loading seems to be taking a while.
