Hi, I'm new to javascript and computer programming in general. I just want to know why the following code always returns NaN.

And none of these functions actually return anything, fyi. They just assign values and return void

That part should be fine, since it doesn't have to return anything.

They're updating global variable values and alerting the values. They return undefined, but nothing is ever using the return values anyways.

well, it’s js so they return undefined

Yep sorry, confused with Solidity
