probably not true in most other langauges. although I’m not well versed in the way numbers are represented in code and what makes a number “NaN”, something tells me the technical implications of that would be quite bad in a production environment.
the definitive way to check for NaN in JS would probably be something like
// with `num` being an unknown value
// Convert value to a number
const res = Number(num);
/*
* First check if the number is 0, since 0 is a falsy
* value in JS, and if it isn't, `NaN` is the only other
* falsy number value
*/
const isNaN = res !== 0 && !res;
no. events and our decisions are abstracted far enough so that the illusion of free will is apparent. I think it’s very well impossible to fully distinguish between free will and fate from our limited perspective
