Number.POSITIVE_INFINITY

`Number.POSITIVE_INFINITY` is a special numeric value
that is returned when an arithmetic operation or
mathematical function generates a value greater than the
largest representable number in JavaScript (i.e., greater
than `Number.MAX_VALUE)`.

JavaScript displays the `POSITIVE_INFINITY` value as
`Infinity`. This value behaves mathematically like an
infinity--for example, anything multiplied by infinity is
infinity, and anything divided by infinity is zero.

Note that when numbers "underflow," i.e., when they become
less than `Number.MIN_VALUE,` JavaScript converts them
to zero.
