Silly question - why are is everybody talking about jQuery in the past tense and why are you saying it "did not succeed"?
It just got a beta release of a major version less than a week ago, it's a core part of Bootstrap, which just about anyone building webapps has used at some point, and depending on whose statistics you look at[1], powers a frankly absurd number of sites, including things everyone's heard of like Microsoft and Yahoo and Amazon.
That's the opposite of a has-been thing that did not succeed in my book.
