What is the “right” JSON date format? to retrieve a subset of the data, as discussed in things get complicated. It's more constrictive than only ruling out circular references, because it also rules out ever printing an object twice, one of the side affects of which is to avoid circular references. under both Ada's record and under the group. But at least it does not have exponential complexity. !value.constructor ? This is nice, although it's removing duplicates as well, not just circular links. Figure out a way to populate the replacement array with cyclic references. When you use JSON.decycle(variable, true) you accept the fact that the result will not be reversible (retrocycle will not re-create DOM nodes). Excellent !!!
