Optional_convertFunction: ((val: NumberType) => U)Compares this object's fields to another object's fields for equality. Equality is determined by comparing the JSON representations of the objects.
If normalizeNumberTypes is true, then all number types will be compared as strings (i.e. "1n" === "1" === 1). Else, they will be compared as their native types (i.e. 1n !== 1 !== "1").
OptionalnormalizeNumberTypes: boolean
Base class that implements the CustomType interface. It provides default implementations for all methods. This is to be used when the class and all of its fields are of primitive types (i.e. no number types).
