Global Properties
The
global object is not a class, so the following global properties have
individual reference entries under their own name. That is, you can

“Global.undefined.” Note that all top-level variables are
also properties of the global object.
-
Infinity A numeric value that represents positive infinity.
-
NaN The not-a-number value.
-
undefined The
undefinedvalue.
