Promises, under the hood

You all know that to create a new Promise you need to define it this way:

  new Promise((resolve, reject) => {
    ...
    resolve(someValue)
  })

You are passing a callback that defines the specific behavior of your promise.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
