Ignore circular references

[muuvmuuv]

I am trying to tidy our codebase and replace all of our _.deepClone stuff with Klona or with simpler solutions where it fits. Unfortunately, in one case where a deep clone is required, we have a circular ref that we cannot remove at this point. Would it be possible for Klona to ignore a circular ref or add some option how to handle these, so we could ignore it?

I expect something like

const circRef = {...}
const cloned = klona(circRef, {
  onCircularReference(ref) {
    return undefined
  }
})

I am also happy with any package that removes circular references, but I would love to have both in one place.

Seems out of scope since the project is solely focused on cloning... however I do see the appeal of avoiding additional looping if you're working with gigantic objects or need to do a huge number of clones.

For the time being, if your objects are JSON serializable you can use the replacer parameter of JSON.stringify. There's a good example on MDN. Otherwise I'd just loop with similar logic.

Unfortunately it is more complex since its the input of our apps logs and therefor it can be ANY valid JS object. I fiddled something together and will try it this week. Maybe it can be another file "circular" of you are interested. Anyway will post my changes as soon as I have something together.

Ok, I will post my PR soon, no need to accept it. I also made some other adjustments which besides the circular might be a good fit.
