What is InstanceType?
InstanceType is a conditional type in TypeScript that extracts the instance type of a constructor function type. In simpler terms, given a type that represents a class or a constructor function, InstanceType determines the type of the object that would be created when you use the new keyword with that constructor. This allows you to easily work with the specific type of instances generated by a class constructor within your type system.
