Does JavaScript adhere to a particular pattern?

Question

Does JavaScript adhere to a particular pattern?

Is there a more streamlined approach to implementing this particular design pattern?

function a() {
    function x() { /* code */ }
    function y() { /* code */ }
    /* additional code */
    x(); y(); // can be called from here
}

a();
a.x();
a.y();

I recently learned about prototypes, so I thought of using something like this:

a = function() { }
a.prototype.x = function() { }
a.prototype.y = function() { }

But is there a simpler method? Considering that in my code a also belongs to the prototype of something else, such as

function plugin() { ... }
plugin.prototype.a = function () {}
plugin.prototype.a.prototype.x = function () {}
plugin.prototype.a.prototype.y = function () {}

Answer №1

You have the option to create your code blocks in this manner:

function example() {
    this.alpha = function () { /* custom code */ }
    this.beta = function () { /* custom code */ }
    /* additional code */
    this.alpha(); this.beta(); // execute these functions here
}

var testCode = new example();
testCode.alpha();
testCode.beta();

}

var testCode = new example();
testCode.alpha();
testCode.beta();

Why not define a function *a* in a simple way like this:

function a( x , y){
   x();
   y();
}

And call it like this:

x = function(){
 // some code
}

y = function(){
 // some code
}

a(x,y);

Or even like this:

a(
function(){
  // some code
},
function(){
 // some code
}

);

Even if 'a' belongs to someone else's prototype.

You can still do this:-

someOtherObj.prototype.a = function( x , y){
       x();
       y();
     }

And when calling, just pass x and y either after defining or anonymously.

To ensure your code remains organized and free from conflicts, consider implementing the singleton or module pattern:

var example = function(){
  // private variables
  var variable;
  method: function(){return variable;}

  // public methods go here
  return {
    getMethod: method
  }
}();

Only the methods returned through return are accessible externally, everything else is encapsulated within the object.

If you're in search of JavaScript tools that facilitate dynamic object composition as outlined in your query, consider utilizing three key functions from the Object entity (note that these functions require JavaScript 1.8.5):

For those seeking specific Design Patterns, various approaches touch upon elements raised in your question. However, for a building block-oriented strategy like the one central to your inquiry, I recommend exploring the Composite Pattern and Mixin Pattern described in the following sources:
