There was a problem hiding this comment.
let id = 0;
const seen = new WeakMap<object, number>(); // ref -> counter
// then
if (seen.has(value)) {
return `[Circular ref${seen.get(value)}]`;
}
seen.add(value, id++);By doing like this, it would be useful for cross-boundary and recover the circular reference to the original JSON (in the future)
