How can I use CommonJS modules to extend eachother or create inheritance? (This is pseudo code)

module-a-ext.js

var ModuleA = require('module-a');

function ModuleAExt() {
  
  ModuleA.prototype.change_name = function(name) {
    this.name = name;  
  };
  
  return ModuleA;
}

module.exports = ModuleAExt;

module-a.js

function ModuleA() {
  this.name = "module-a";
}

module.exports = ModuleA;
