How To Share State Across React Components with Context
In this tutorial, you’ll share state across multiple components using React context. React context is an interface for sharing information with other components without explicitly passing the data as props.

Using Event Emitters in Node.js
Event emitters are objects in Node.js that trigger an event by sending a message to signal that an action was completed. In this article, you will create an event listener for a TicketManager JavaScript class that allows a user to buy tickets. You will set up listeners for the buy event, which will trigger every time a ticket is bought. This process will also teach you how to manage erroneous events from the emitter and how to manage event subscribers.
