Bundle everything? Yep. Self contained? Yep. 10 components that open connections to 10 different severs? Yep.
The web is so massive that there is a way for pretty much everything (though for some reason webdevs try not to admit this).
This is mostly because if you can keep development paradigms consistent within your job, that is one less thing to whack-a-mole in the fun game of "with permutation X of the endless combination of browser (and version), OS (and version), etc. why isn't the thing working?"
My understanding is that he is correct - in terms of requiring a framework to be bundled with your code. Svelte is not a framework that needs to be bundled with your code, instead it injects helper code during the transpilation step and the result has no dependencies.
If I'm incorrect I'd appreciate the trigger happy person to explain why rather than killing this comment.
