The whole point is to not let V8 do any job at all.

V8 == user impacted.

Compile time V8 == compiler impacted, users happy.

It's like interpreting what you can during compile time, with caching capabilities.

To speed up boot time and init time, not runtime per say.

This. By transforming and evaluating things that really could be constants beforehand, V8 has less to do when it goes to run the javascript.
