API Calls & Framework... IDK

Inexperienced programmer (just started a week ago, no shit I'm just now understanding why classes rock so hard.). If making API calls to linked libraries in statically compiled binaries is faster than using a framework that uses JiT compilation... why do so many people push for the framework and JiT compilation?

I'm not trying to start anything, but I'm seriously curious as to why the later is the preferred choice.

``Computer Science'' is a branch of Mathematics and thus abstract. Implementation details may matter in Software Engineering, but not in CS. You don't know shit about programming.
