Description:
JSConstDoubleSpecs is typically used to define a set of double values that are assigned as properties to an object using JS_DefineConstDoubles. JS_DefineConstDoubles creates one or more double properties for a specified object.
JS_DefineConstDoubles takes an argument that is a pointer to an array of JSConstDoubleSpecs. Each array element defines a single property name and property value to create. The last element of the array must contain zero-valued values. JS_DefineConstDoubles creates one property for each non-zero element in the array.
