Reflect.setPrototypeOf()

The Reflect.setPrototypeOf() static method is like Object.setPrototypeOf() but returns a Boolean. It sets the prototype (i.e., the internal [[Prototype]] property) of a specified object.

Reflect.setPrototypeOf() provides the reflective semantic of setting the prototype of an object. At the very low level, setting the prototype returns a boolean (as is the case with the proxy handler). Object.setPrototypeOf() provides nearly the same semantic, but it throws a TypeError if the status is false (the operation was unsuccessful), while Reflect.setPrototypeOf() directly returns the status.

Reflect.setPrototypeOf() invokes the [[SetPrototypeOf]] object internal method of target.

Syntax example: Reflect.setPrototypeOf(target, prototype)
