Summary
In this chapter, we discovered Node.js for the first time. You should now have a good idea of the core principles (such as event loop, threads, modules, and packages) upon which Node.js was built. You have read a bit about Node.js’s history and why V8 was chosen as the JavaScript engine.
One of the key things to take away from this chapter is how the event loop works. Note that part of this knowledge is not exclusive to Node.js. The distinction between micro tasks and tasks is an integral part of how JavaScript engines, even the JavaScript engine of your browser, work.
Lastly, you are now equipped to use the node command-line application, for example, to run or debug simple scripts, which can export and import functionality using the CommonJS module system. You learned how to use the Chrome web browser to inspect Node.js scripts as you can with websites.
In the next chapter, we will increase our knowledge about CommonJS by learning how we can efficiently divide code into modules and packages.
