Name

Infinity — a numeric property that represents infinity

Synopsis

Infinity

Description

Infinity is a global property that contains the special numeric value representing positive infinity. The Infinity property is not enumerated by for/in loops and cannot be deleted with the delete operator. Note that Infinity is not a constant and can be set to any other value, something that you should take care not to do. (Number.POSITIVE_INFINITY is a constant, however.)
