Async Lock

Definitions

1. A synchronization primitive used in asynchronous code to ensure only one task or a limited set of tasks can enter a critical section at a time without blocking an entire thread. Async locks are important when shared state must be protected inside event-loop or cooperative-concurrency systems.

   In plain English: A lock used in async code to coordinate access to shared state without blocking everything.

   Example: "They added an async lock around token refresh so ten concurrent requests would not all trigger duplicate refresh calls."
