Last time I checked, Node is nowhere close to displacing Java (and Spring) for enterprise web computing. C#/.NET is still king in the Windows universe. And, believe it or not, PHP and Ruby are still very widely used. Node has only a small piece of the pie.
Moreover, Golang is providing very strong competition for Node. Node has definite limitations for high-concurrency and high-transaction-rate applications.
Golang can spin up hundreds of thousands of threads (goroutines) without breaking a sweat. Let’s see Node do that.
Node’s single event queue hobbles it for many types of backend applications.
