Operator to test for falsy values with zero treated as truthy

Question

Is there a minimalistic syntax to do the same as x === 0 ? true : !!x. The goal of this expression is to avoid the exclusion of zero as falsy and yet make sure other falsy values do are converted to false.

Answer 1

Basically, you want to allow any number?

typeof x === 'number'

Answer 2

The most minimalist syntax I can think of is

x === 0 || Boolean(x)

Answer 3

I'm not sure that there's a better solution than what you've got. You could also use !!x || x === 0 though
