Your code looks perfect.
No errors. No warnings. Tests pass.

And then production breaks.

This video explains one of the most dangerous silent bugs in JavaScript: JSON.stringify data loss.

JSON.stringify does not serialize JavaScript it serializes JSON.
And JSON has limits.

In this breakdown, you’ll learn:

Why functions, undefined, Symbol, and BigInt silently disappear

How Date objects turn into strings without warning

Why Map, Set, and RegExp lose their meaning

How this causes real production bugs in APIs, caching, logging, and storage

There’s no crash.
No exception.
Just wrong data.

This is why many backend, frontend, and full-stack bugs go unnoticed for months.

If you work with JavaScript, APIs, Node.js, React, or system design — this is a must-know concept.

Remember the rule:
JSON is a data format, not a JavaScript snapshot.

Silent bugs cause the most damage.
