# This file is the source Rails uses to define your schema when running `bin/rails
# db:schema:load`. When creating a new database, `bin/rails db:schema:load` tends to
# be faster and is potentially less error prone than running all of your
# migrations from scratch. Old migrations may fail to apply correctly if those
# migrations use external dependencies or application code.

They provide a more structured and readable way to handle asynchronous code compared to traditional callback-based approaches. A promise represents the eventual completion (or failure) of an asynchronous operation and its resulting value. Promises can be in one of three states: 1. **Pending**: The initial state, when the operation has not completed yet. 2. **Fulfilled**:
