Technical requirements
You should have the latest version of Node.js 14 installed, as well as access to a Terminal. You will also need access to an editor and browser of your choice.
The Optimizing synchronous functions recipe will require the use of MongoDB. We will be using Docker to provision a containerized MongoDB instance. Refer to Chapter 7, Working with Databases, for detailed technical setup information using MongoDB via Docker.
The code samples used in this chapter can be found in the Packt GitHub repository at https://github.com/PacktPublishing/Node.js-14-Cookbook in the Chapter10
