Can this (below) be considered a facade (structural design pattern)?

Question

function BankOperationChecker() {
    //This is the facade
    this.applyFor = function(facadeMethods) {
        for (var method in facadeMethods) {
            facadeMethods[method]();
        }
    }
}

function BankClient(name, amount) {
    this.name = name;
    this.amount = amount;
    this.bankOperations = new BankOperationChecker();
}

var client = new BankClient("Davi Vieira", 2000);
var checkMethods = {
    cleanBackground: function() {
        console.log('The background of this client is clean.');
    },
    canGetCredit: function() {
        if (client.amount > 1000) {
            console.log('Can get credit!');
        } else {
            console.log('Cannot get credit!');
        }
    }
}

client.bankOperations.applyFor(checkMethods);

What do you think? Facade for entrance is just one... but is that right? Is there any specific rules about creating a facade?

Answer 1

No, it can't.

Facade, in English, means 'the face of a building, especially the principal front that looks onto a street or open space'. Because of this, many people confuse Facade pattern as something that acts as an entrance to something else- that, however, is not so.

As per this , the intents behind Facade patterns are:

• Provide a unified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.
• Wrap a complicated subsystem with a simpler interface.

Your example neither has bunch of subsystems nor does it have one interface to wrap all of them.
