JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
Provides a class factory with additional functionality, like mixins
and plugins
. Although originally designed for use with Node.js and installable via npm install cla6
,
it can also be used directly in the browser.
Cla6 is also installable via:
bower install cla6
var Cla6 = require('cla6');
var Parent = Cla6('Parent', {
constructor: function() {
console.log('parent constructor');
},
parentMethod: function() {
console.log('parent method');
}
});
var Child = Cla6('Child').extend(Parent, {
childMethod: function() {
this.parentMethod();
console.log('child method');
},
get accessor() {
console.log('child getter');
},
set accessor(value) {
console.log('child setter');
}
});
child = new Child(); // parent constructor
child.childMethod(); // parent method, child method
child.accessor = child.accessor; // child getter, child setter
Unlike classic class definition, Cla6 defines unenumerable prototype properties:
// Classic class definition
function Klass() {
this.foo = 'foo';
this.bar = 'bar';
}
Klass.prototype.constructor = Klass;
Klass.prototype.baz = function() {
return 'baz';
};
var instance = new Klass();
// prints foo, bar, baz
for (var k in instance)
console.log(k);
// Cla6 class definition
var Klass = Cla6('Klass', {
constructor: function() {
this.foo = 'foo';
this.bar = 'bar';
},
baz: function() {
return 'baz';
}
});
var instance = new Klass();
// prints foo, bar
for (var k in instance)
console.log(k);
Each class created by Cla6 can be extended using a mixin. Mixins can be applied at class creation or during run time.
var mixin1 = {
method1: function() {
console.log('mixin1');
}
};
var mixin2 = {
method2: function() {
console.log('mixin2');
}
};
var mixin3 = {
method3: function() {
console.log('mixin3');
}
};
var Klass = Cla6('Klass', {
constructor: function() {
console.log("klass");
},
}).mixin(mixin1, mixin2);
Klass.mixin(mixin3);
var obj = new Klass(); // klass
obj.method1(); // mixin1
obj.method2(); // mixin2
obj.method3(); // mixin3
A Cla6 plugin is a manupulation function which gets the classe's descriptors and parent anytime before it gets created, thus the properties can be manipulated. Multipile plugins can be applied and will be called by their use order.
Note, each plugin will affect the descriptors object for the next plugin in the plugins chain.
Cla6.use(plugin);

Alternatively, you can install using Node Package Manager (npm
):
