The /data/db directory is the default data directory used by MongoDB to store data files when running as a standalone server or as a replica set.
In earlier versions of MongoDB (prior to 3.2), the /data/db directory was the default location where MongoDB stored its data files. It contained subdirectories for each database, and within each database directory, there were files representing collections and other database-related data.
Node.js is a strong choice for I/O bound applications, data streaming applications, and data-intensive real-time applications, where its event-driven, non-blocking architecture and support for data streaming and bidirectional communication can provide significant advantages.
In Angular, the square brackets [ ] are used to enclose property binding syntax. Property binding allows you to bind a value from the component's class to a property of a DOM element or a directive in the template.
