Reflect.construct()

The Reflect.construct() static method is like the new operator, but as a function. It is equivalent to calling new target(…args). It additionally allows you to specify a different new.target value.

Reflect.construct() provides the reflective semantic of a constructor call. That is, Reflect.construct(target, argumentsList, newTarget) is semantically equivalent to:

Note that when using the new operator, target and newTarget are always the same constructor — but Reflect.construct() allows you to pass a different new.target value. Conceptually, newTarget is the function on which new was called, and newTarget.prototype will become the constructed object’s prototype, while target is the constructor that is actually executed to initialize the object. For example, new.target may also be different from the currently executed constructor in class inheritance.

Syntax example: Reflect.construct(target, argumentsList)
