We're probably going to have to live with "compiler" meaning "bundler" as an ongoing JavaScript-world neologism.
yeah it's not but i don't know how to call it. if i say it's bundler it will be more confusing in my opinion. waiting for your suggestions!
Sometimes the term "packager" is used instead of "bundler". Honestly though, "compiler" is the term most likely to cause any confusion. Even if one is not familiar with packagers/bundlers "js to exe ${unknown phrase}" still conveys things more clearly than "js to exe ${misleading phrase}".
But it's definitely not a compiler! I think "Astra - a new js2exe bundler" is much less ambiguous because it's... a bundler!
