advanced patterns with JSON.stringify and Map objects in Node.js
I'm converting an old project and I'm working with an scenario with serializing a Map object into JSON using `JSON.stringify` in Node.js v18.0.0. When I try to convert a Map to JSON, it doesn't seem to serialize correctly and ends up as an empty object. Here's the code I'm using: ```javascript const myMap = new Map(); myMap.set('key1', 'value1'); myMap.set('key2', 'value2'); const jsonString = JSON.stringify(myMap); console.log(jsonString); // Output: {} ``` I expected the output to reflect the entries in the Map, but it returns `{}` instead. I know Maps are not directly serializable to JSON because they don't have a standard object structure. So, I've tried to convert the Map to an array of entries first: ```javascript const jsonString = JSON.stringify(Array.from(myMap.entries())); console.log(jsonString); // Output: [["key1","value1"],["key2","value2"]] ``` This works, but it feels a bit clunky compared to just using `JSON.stringify` directly. Is there a more elegant way to serialize a Map while maintaining its structure? Additionally, are there any performance implications in terms of using `Array.from()` for larger Maps, or is there a more recommended approach in modern JavaScript? Any insights would be greatly appreciated!
