Different ways of defining classes in ES5 and also how to inherit from another class

ES5 Classes.js

// class
var Person = function(name, gender) {
  this.name = name;
  this.gender = gender;
  this.legs = 2;
}

Person.prototype.getName = function () {
  return this.name;
}


// class
function Car() {
  var make = 'mazda';
  var model = '323';
  
  var getMake = function () {
    return make;
  }
  
  return {
    getMake: getMake
  }
}

// var femi = new Person('Femi Abolaji', 'male');

function man(name, gender) {
  this.name = name;
  this.gender = gender;
}

man.prototype = new Person();

var tunde = new man('Tunde will', 'male');
tunde.getName();
tunde.legs;
