Node’s event-driven architecture allows us to execute certain actions when something happens. This is done via objects (called “emitters”) which can emit named events that cause functions (“listeners”) to be executed. Objects that emit events are instances of node’s EventEmitter class, made available via the events module. In this article we’ll look at node’s event emitter.
ACID stands for Atomicity, Consistency, Isolation, and Durability. It is a set of database properties(rules) which transactions must obey to maintain the integrity and consistency of a database. In this article we’ll take a look at each ACID property.
D.R.Y, which stands for “Do Not Repeat Yourself”, is a principle of software development aimed at reducing the repetition of code.

Speed performance is critical in modern day applications. Most of the times your application may have to make requests to an endpoint/server to get some data. Or your application may frequently request a specific dataset.
Depending on the size of your dataset a long with other things like query database and network speed, the speed at which your application can fetch certain data to display to users may get slower over time (as data increases).
This is where caching comes in handy and can dramatically improve your application’s speed.
