esid: sec-atomics.isLockFree
description: >
  Atomics.isLockFree returns a boolean that indicates whether
  operations on datum of size will be performed without the agent
  acquiring a lock outside of size bytes.
info: |
  Atomics.isLockFree( size )

  1. Let n be ? ToInteger(size).
  2. Let AR be the Agent Record of the surrounding agent.
  3. If n equals 1, return AR.[[IsLockFree1]].
  4. If n equals 2, return AR.[[IsLockFree2]].
  5. If n equals 4, return true.
  6. If n equals 8, return AR.[[IsLockFree8]].
  7. Return false.
