method Deno.AtomicOperation.prototype.check
import { Deno } from "https://deno.land/x/deno@v1.41.0/cli/tsc/dts/lib.deno.unstable.d.ts";
const { AtomicOperation } = Deno;

Add to the operation a check that ensures that the versionstamp of the key-value pair in the KV store matches the given versionstamp. If the check fails, the entire operation will fail and no mutations will be performed during the commit.
