50 cards
It's a great fit if you're starting out with Node.js, transitioning from another backend stack, or preparing for technical interviews where runtime behavior often comes up. Even developers who use Node daily can benefit, because the cards encourage you to articulate the "why" behind mechanics you may otherwise take for granted.
To get the most out of these cards, try to connect each concept to a real scenario rather than memorizing isolated definitions. For example, when reviewing the event loop phases, mentally trace what happens during a typical file read or HTTP request. Spacing your review sessions across several days will help the more intricate distinctions, like CommonJS versus ESM or the middleware execution order, move into long-term memory. If a card feels tricky, revisit the related cards nearby first to build context before tackling the harder one.
