The Hidden Trap: JavaScript IEEE 754 & Large IDs
In modern distributed systems (like Twitter Snowflake IDs or database 64-bit BigInts), IDs often exceed 53 bits (e.g. 1824982739482716391).
When JavaScript parses standard JSON via JSON.parse(), numbers exceeding Number.MAX_SAFE_INTEGER ($2^{53} - 1 = 9007199254740991$) silently lose precision and round to nearby numbers:
`javascript
const raw = '{"id": 1824982739482716391}';
const parsed = JSON.parse(raw);
console.log(parsed.id); // 1824982739482716400 (Corrupted!)
`
Solution: High-precision IDs must always be serialized as quoted strings in JSON payloads ({"id": "1824982739482716391"}).
Troubleshooting Circular References
Attempting to serialize an object that references itself via JSON.stringify(obj) throws a TypeError: Converting circular structure to JSON. Use a custom replacer or tree-walker to safely serialize complex state graphs.
