I'm struggling with a unique tree data structure in my code. Each node is represented by an object, and I need to transfer the entire tree to the front-end. Unfortunately, JavaScript's limitation on using objects as keys prevents me from implementing the following solution:
tree = {{}:{{}:{}, {}:{}, ...}, ...}
Is there an alternative method I can use to achieve this task? And how should I go about parsing the tree back in the front-end?
If you want to convert your data into a format that can be easily serialized, like JSON, it's important to structure your data in a way that doesn't rely on objects as keys in a Map. Make sure that each object has a unique identifier, such as an ID property. If there isn't one already, you can create a sequential number for each object. Then, encode your data using these identifiers as keys. This will allow you to serialize and deserialize your data using JSON.
