The Web Locks API, available in secure contexts, allows scripts in different tabs or workers to acquire and release locks, coordinating work and resource usage in web apps. Locks are requested with a name and optional options like mode, ifAvailable, steal, and signal for advanced functionality. Deadlocks can occur if locks are requested out of order, but strategies like avoiding nested requests can prevent them. The API provides methods for querying the state of locks for debugging purposes. The Lock and LockManager interfaces enable requesting and managing locks. This unique feature helps maintain order and efficiency in web app development.
