Setup

function T() {
    }
    
    T.prototype.myMethod = function(i) {
      if (i == 20000) {
        console.log('Hey T!');
      }
    };
    
    function Tt() {
      this.myMethod = function(i) {
        if (i == 20000) {
          console.log('Hey Tt!');
        }
      };
    }
    
    function Dd() {
    return this.prototype = {myMethod : function(i) {
        if (i == 20000) {
          console.log('Hey Tt!');
        }
      }
    };
