how to return same reference using c++ pointer ? and returning reference maybe memory leak ?

[tommyZZM]

// c++
class SomeThing {
  
  SomeThing() {};
  
  ~SomeThing() {};

  SomeThing* getRef() {
    return this;
  }
  
}

NBIND_CLASS(SomeThing) {
  method(getRef);
}

// javascript
const a = new SomeThing();
console.log(a.getRef() === a.getRef()); // false

Will this make memory leak while calling the.getRef() method ?
