The Infinity global property is a numeric value representing infinity.
{{InteractiveExample("JavaScript Demo: Infinity")}}
```js interactive-example const maxNumber = 10 ** 1000; // Max positive number
if (maxNumber === Infinity) { console.log("Let's call it Infinity!"); // Expected output: "Let's call it Infinity!" }
console.log(1 / maxNumber); // Expected output: 0
## Value
The same number value as {{jsxref("Number.POSITIVE_INFINITY")}}.
{{js_property_attributes(0, 0, 0)}}
## Description
`Infinity` is a property of the _global object_. In other words, it is a variable in global scope.
The value `Infinity` (positive infinity) is greater than any other number.
This value behaves slightly differently than mathematical infinity; see {{jsxref("Number.POSITIVE_INFINITY")}} for details.
