sextend v1.0.0
sextend
sextend ("super extend") allows you to to do inheritance in JavaScript and in much the same manner as util.inherits in Node.js, except now you also inherit class variables too! Isn't that cool?
For further awesome, you can also add mixins at the same time!
Usage
For extending, just use it like you would use util.inherits in node.js.
In node:
var sextend = require('sextend');
function A(){}
A.coolStaticVar = "fun";
function B(){}
sextend(B, A);
console.log(A.coolStaticVar); // funIn browser:
<script src="sextend.js"></script>
<script>
function A(){}
A.coolStaticVar = "fun";
function B(){}
sextend(B, A);
console.log(A.coolStaticVar); // fun
</script>For mixins, you can add extra arguments that are mixin functions. A mixin
function is just a function that refers to the destination object as this and
adds properties accordingly.
Example:
function A(){}
function MyMixin(){
this.prototype.instanceVar = 1;
this.staticVar = 2;
}
sextend(A, null, MyMixin); // superclass is optional
console.log(A.staticVar); // 2
console.log((new A()).instanceVar); // 1License
