Use type instead of interface

[ryanleecode]

Proposed changes

Using interface for base types causes a lot of bullshit when it comes to generics trying to consume this type because of index signatures.

All the interface signatures should be converted to type

For example the current type signatues cause a lot of problems when trying to make it a deserialization JSON type

type JsonPrimitive = string | number | boolean | null | undefined | Date | symbol;
type JsonArray = Json[];
type JsonRecord<T> = {
    [Property in keyof T]: Json;
};
type Json<T = any> = JsonPrimitive | JsonArray | JsonRecord<T>;
