Is there a way to identify if a variable is simply a reference to another object, and if so, determine the original variable name?
For example, when trying to json encode an object that contains a property referencing back to the original object, it can lead to an infinite loop. Is there a method to test if a property is a reference and indicate it as such without having to reconfigure the original object?
let myObject = {'example': 'content'};
let anotherObject = myObject;
After this assignment, myObject and anotherObject are essentially the same, meaning they both reference the exact same object in memory. There is no direct relationship between myObject and anotherObject, so one is not a reference to the other; rather, they point to the same object.
While JavaScript does not support references to other variables directly, for detecting circular references - a scenario you may encounter - there are more suitable methods provided here: Is there a way to test circular reference in JavaScript?
Furthermore, when using native JSON encoding with JSON.stringify(), it automatically handles checking for cyclic objects:
>>> let obj = {};
>>> obj.y = obj;
>>> JSON.stringify(myObject)
TypeError: cyclic object value
