module pattern

In JavaScript, the Module pattern is used to further emulate the concept of classes in such a way that we’re able to include both public/private methods

var personModule = (function () {

    var firstName;
    var lastName;

    return {
        setName(f, l) {
            firstName = f;
            lastName = l;
        },
        getName() {
            return firstName + " " + lastName;
        }
    }

})();

personModule.setName('akash', 'pal')
personModule.getName() //"akash pal"
