More like 200 lines, so it is useful to have a library. BTW it is rare to hear component lifecycle and event system described as key selling points of React. Most people would say DOM diffing and perf are the key selling points.

Right - DOM diffing is the key selling point of React. But the fine-grained screen updates possible via DOM diffing is not super important for most applications.

Event system is already supported by DOM. React doesn't add anything there. Component lifecycle is also not compelling.
