Nowadays several misconceptions are heard about Node.js.Some of them are mentioned and explained here.
The Event loop runs in a different thread
The Node.js work on an event driven mechanism that means the flow control is defined by a set of phases for a particular event.
There is a misconception that the main thread will hand over the work to the event loop thread and when the work is over the event thread will execute a call back. But the Event Loop itself is a separate thread as Node.js provides a Single threaded environment.And then the event loop calls for different tasks as per the requirement of the part of the network application.
The event loop is just like a Stack or Queue
It is said that the event thread works on the concept of Stack or Queue but the reality is there are some structures involved in the JS and the event loop goes through some phases and the event tasks are performed in a continuous manner. The Event loop works on the concept of phases and in every phase there are a handful of tasks and callbacks which are executed in a first in first out concept i.e FIFO concept.
One can not use a type-safe way for Node.js apps
The event looping is blocked by all the CPU intensive functions.
The CPU-intensive functions blocking all the Node.js event loop but this is a myth i.e. it is not 100% true.Node.js world on the concept of single threaded environment therefore it can not run more than one part of the application in a parallel manner but this can be achieved by using IO process management operations asynchronously. The synchronous part of the application i.e. hundreds of the clients connected at the same time may take a longer waiting time for all of them because of the extremely large Array. However CPU operations do not block all the event loops by Node.js, for example crypto.randomFill() , crypto.randomBytes().
Compatible with Chrome V8 only
It is said that node.js can only rely on Chrome V8 whereas the truth is Node.js is an open source and cross-platform system which is used for building network applications. Therefore it is true with the compatibility part of Node.js It is flexible and smooth working with many Operating Systems.
Node.js works slow
Difficult to program any network application using Node.js
