No-Parameterized constructors are a code smell of an **invalid* object that will dangerously mutate.
Incomplete objects cause lots of issues.*

TL;DR: Pass the essence to all your objects so they will not need to mutate.

Problems

• Mutability

• Incomplete objects

• Concurrency inconsistencies between creation and essence setting.

• Setters

Solutions

Examples

• Some persistence frameworks in static typed languages require an empty constructor.

Exceptions

• Stateless objects. Always better solution than static class methods.

Sample Code

Wrong

class AirTicket {
   constructor() {     
  }
}

Right

class AirTicket {
   constructor(origin, destination, arline, departureTime, passenger) {     

  //...     
  }
}
