Asynchronous, Events, Node architecture

Node.js Architecture

• node someFile.js will start the event loop process in synchronous-land
  • will end process after it knows there is nothing else to do
• when asynchronous is present, the event loop stays active until the asynchronous event is finished.
  • will often return something with a callback
  • if there is no callback, the loop will not stay active waiting for a response
  • follows completion order not dispatch order

Code Reviews: Its not kindness, its diplomacy

Elodie Rafalimanana https://tinyurl.com/ydez8v94

The Problem

• developers argue about code during a code review
  • "It does not make sense, its a horrible idea, you're doing it wrong, its just cosmetics"
• causes inertia and animosity = inefficient
• What are they actually arguing about?

• Classes must implement Serializable
  • no methods to implement
• ObjectOutputStream performs serializing / ObjectInputStream perofrms deserializing
