I know this is for fun, but as general advice to the homies, if a language or system is doing something you didn't expect, make sure to look at the documentation

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt

This will save a lot of time and headaches

oh god the reason is even stupider then I expected

Because large numbers use the e character in their string representation (e.g., 6.022e23 for 6.022 × 1023), using parseInt to truncate numbers will produce unexpected results when used on very large or very small numbers. parseInt should not be used as a substitute for Math.trunc().
