Call and apply with classes and what how can you use in in a best way

function emp()

{

  console.log("called");

}

emp.prototype.getEmpSalary=function(salary)

{

   const totalSalary=salary*12;

   return totalSalary;

}

emp.prototype.empType=function(salary,type)

{

   let salaryObject={};

   switch(type)

{

      case  "it" :

      salaryObject.type="it emp";

      salaryObject.salary=salary*12;

      break;

      case  "others" :

      salaryObject.type="others emp";

      salaryObject.salary=salary*12;

      break;

}

   return salaryObject;

}

var manish=new emp();

function callEmp(s)

{

  //invoke a function emp using call

  console.log(emp.prototype.getEmpSalary.call(this,s));

 //invoke a function emp using apply

 console.log( emp.prototype.empType.apply(this,[2000,"it"]));

}

callEmp(20000);

//deference between call and apply call work on number of argruments passed while apply works on array 

//object assign extending object with new properties

function languageType()

{

   this.name="java";

   this.type="Object Oriented";

}

var java=Object.assign(languageType,{version:8});

console.log(java.version);
