    Infinity is a property of the global object, i.e. it is a variable in global scope.

    The initial value of Infinity is Number.POSITIVE_INFINITY. The value Infinity (positive infinity) is greater than any other number. This value behaves mathematically like infinity; for example, any positive number multiplied by Infinity is Infinity, and anything divided by Infinity is 0.

    Per the ECMAScript 5 specification, Infinity is read only (implemented in JavaScript 1.8.5  / Firefox 4).
