#Rule Details

Disallows incorrect usage of new and constructor in interfaces and classes. Interfaces define the shape of objects but cannot be constructed directly; defining a new() construct signature in an interface that returns the interface type or a constructor method signature is almost always a mistake. Similarly, classes should not have a method literally named new that returns the class type, as the constructor keyword should be used instead.

Examples of incorrect code for this rule:

interface Foo {
  new (): Foo;
}

interface Bar {
  constructor(): Bar;
}

class Baz {
  new(): Baz;
}

Examples of correct code for this rule:

class Foo {
  constructor() {}
}

interface Bar {
  new (): SomeOtherClass;
}

interface Baz {
  method(): void;
}
