Que.1 Create a Function

  function Check(obj1){
    obj1.setter = function() {
      console.log(obj1.name);
    }
  }
        

Que.2 Delete a Parameter

  function Check(obj1, rollno) {
    // Check if the object has the `rollno` property
    if (obj1.hasOwnProperty("rollno") && obj1.rollno === rollno) {
      // Delete the `rollno` property
      delete obj1.rollno;
      return true;
    } else {
      return false;
    }   
  }
        

Que.3 Check whether the Package is Dream Package or not

  function Check(obj1) {
    if (obj1.salary > 500000) {
      return "Dream";

      return "NotDream";
    }
  }
        

Que.4 Check whether the Object has a parameter or not

            
  function Check(obj1) {
     if (Object.keys(obj1).length === 0) {
      return false;
    } else {
      return true;
    }
  }
        

Que.5 Merge the Objects

            
  function Check(obj1,obj2) {
      return {
      name: obj1.name,
      id: obj1.id,
      state: obj2.state,
      code: obj2.code
    };
  }
        

Que.6 Object Multiplyer

  function Check(a,{id, houseno}) {    
      return { id: id * a, houseno: houseno * a };
  }
        

Que.7 Find the sum of Object Members

  function Check({ p1, p2, p3 }) {    
      return p1 + p2 + p3;
  }
        

Que.8 Check whether the Objects are same or not.

            
  function check(obj1,a,b) {
      if (obj1.name === a && obj1.id === b) {
      return true;
    } else {
      return false;
    }
  }
