SolutionBack of Card

The "in" Operator

Mapped types iterate over union keys using the `in` operator. They let you dynamically map or transform property modifiers like `readonly` or optional flags `?`.

type Readonly<T> = {
  readonly [P in keyof T]: T[P];
};

How the Platform Works

Review how easily you can subscribe to topics, manage your learning schedules, review digital decks, and monitor active queue metrics.

STEP 01 / PORTAL ACCESS

Create an Account & Search Topics

Sign up securely using JWT-based credentials. Once inside the user portal, use the search box to discover curated technology topics or type in any topic of your choice.

💡 Tip: If a topic is not in the database, the **AI generation mechanism** triggers a call to Gemini, creating a brand new topic with 3 educational flashcards on the fly!

STEP 02 / PREFERENCES

Customize Your Weekly Schedule

Set which topic you want to study on each day of the week. Our backend database ensures that you receive at most one flashcard per day, mapped to your daily selection.

Change your preferred days dynamically from the scheduler dropdown grid. Easily remove scheduled subscriptions at any time with a single click.

STEP 03 / DELIVERY

Get Daily Flashcard Learning

At 9:00 AM, the BullMQ background queue scheduler checks daily subscriptions, retrieves cards you have not studied yet, and emails you a clean, mobile-responsive HTML flashcard.

Flip the card physically or open your email to review code snippets, detailed explanations, and key engineering tips.
