or "shared"

. LockManager
is the object returned by navigator.locks
.
// Should show "exclusive" (the default) navigator.locks.request("my_resource", show_lock_properties); // Should show "exclusive" navigator.locks.request("my_resource", {mode: "exclusive"}, show_lock_properties); // Should show "shared" navigator.locks.request("my_resource", {mode: "shared"}, show_lock_properties); function show_lock_properties(lock) { console.log(`The lock name is: ${lock.name}`); console.log(`The lock mode is: ${lock.mode}`); }
