(assuming you confused CJ with TJ) This just is not true Having coworkers who personally knew TJ, he was a brilliant mind in his own right, and even if you think that is true, reimplementing functionality in another language but sticking with that languages current design patterns, working within the confines of that languages quirks to provide a cohesive, fluent, and extensible API is no small task.
What the parent posted isn't a criticism, they never said it was a small task or that TJ Holowaychuck's work in the nascent Node ecosystem wasn't brilliant. Just that there is low-hanging fruit available when a new technology of the NodeJS type arrives. If someone has the drive and skill to build high-quality [re]implementations of a large number of key libraries, based on what is available in other (much more established) platform/s, then all being well, that person can do it quite rapidly as the problem space has already been mapped (which then in turn has a huge catalytic effect, particularly as all the APIs they create will follow common patterns).
