Problem with large odd numbers in Google Chrome. What could be the problem?

Question

Google Chrome

Hello!
Found this problem. I make an AJAX request to the server and for example a response comes

{'pk': 17849640217091236}

But I sent another response from the server

{'pk': 17849640217091237}

Then I typed in the browser debugger just the number 17849640217091237 and got the following result

. What could be the problem?

Answer 1

If it's just an identifier, pass it as a string.
This is a precision issue - double precision has a limit too.

Answer 2

console.log(Number.MAX_SAFE_INTEGER)
