Re: The curious case of if-not
#2The two if statements given aren't logically equivalent; an equivalent version of the 2nd one would be:
if (!(input.command === "foo" && isValid(input))) {
...
}
You can flip the negation by swapping the if/else blocks, but only if there is an else. Then you also get into questions about whether or not it matters which block is on top.

OP here. Yeah, I should have made it clearer, thanks.
