I'd actually say that JavaScript is the weak point of Node.js. It's got some good points, to be sure, but there's plenty of pitfalls (let's talk string concatenation vs addition, for instance) and the new language extensions of ES6 add more opportunities for confusion until people are very well adapted to them. But as far as providing a nice nonblocking event loop, and a consistent ecosystem built around that event loop, it's pretty neat.
