line?.length === 0will be falsy even iflineisundefined. If thetscoptionnoUncheckedIndexedAccessis enabled, array dereferences always run the risk of beingundefined. Thus, the call toJSON.parsewill generate errors. Changing the emptiness test to!line || line.length === 0closes off this possibility and makes theJSON.parsecall happy.
