function cachedDataVersionTag
Usage in Deno
```typescript import { cachedDataVersionTag } from "node:node__v8.d.ts"; ```
cachedDataVersionTag(): number
Returns an integer representing a version tag derived from the V8 version,
command-line flags, and detected CPU features. This is useful for determining
whether a `vm.Script` `cachedData` buffer is compatible with this instance
of V8.
```js
console.log(v8.cachedDataVersionTag()); // 3947234607
// The value returned by v8.cachedDataVersionTag() is derived from the V8
// version, command-line flags, and detected CPU features. Test that the value
// does indeed update when flags are toggled.
v8.setFlagsFromString('--allow_natives_syntax');
console.log(v8.cachedDataVersionTag()); // 183726201
