Is it possible to simulate constants in Javascript using closures?

Question

Is it possible to simulate constants in Javascript using closures? If so, can you please furnish me with an example?

Answer 1

To declare :

function globals(){
    const x1="something";
    const x2="otherthing";

    return{
      getX1=function(){
        return x1;
      },
      getX2=function(){
        return x2;
      }
    }
 }

var globalConstants=globals();

To access :

globalConstants.getX1();
