$inc increases or decreases numeric values atomically. Useful for counters or scores.
Quick Answer
$inc atomically increments (or decrements) a numeric field by the given amount. db.products.updateOne({_id: id}, {$inc: {stock: -1, views: 1}}). Decrements if the value is negative. Atomic - safe for concurrent updates (no read-modify-write race condition). Commonly used for counters, inventory tracking, and vote counts.
