Node.js Architecture - is Node single threaded? multi threaded?

In this lesson we are going to talk about Node.js Architecture, and while doing so we will try to answer the question: Is Node.js single-threaded or multi-threaded?

Understanding Node.js architecture, and the job of the main thread will help you understand why your Node.js server is slow, it will also help you answer the question: Is Node.js the right tool for the job?

Here is a few links that we visited during the lecture:
Nodejs worker_threads module: https://nodejs.org/docs/latest/api/wo...
Node.js example of main thread starvation that originates from the C++ section: https://nodejs.org/en/learn/getting-s...
image of the architecture is available here:   / nodejs-architecture
