It is already in use by a huge number of websites and autodownloaded by most browsers. Benchmarks show that the best alternative framework is less more than twice as slow and everyone's favourite jQuery is four times slower. Just think of all that speed you are giving up! Other benchmarks reveal an even bigger advantage for Vanilla JS .
