es6like-class v0.2.4

es6like-class

Write es6 like classes in es5 with a few more features

Cover some limitations to the current implementation of classes in es6:

• define properties
• use traits

Use

var newClass = require('es6like-class').newClass;

var A = newClass({
    constructor: function A(value) {
        this.initialized = value;
    }
});

var B = newClass({
    extends: A,

    constructor: function B(value) {
        assert.strictEqual(this.constructor, B);
        this.bValue = value;
    }
});

Class special properties

• abstract: set the class as abstract
• constructor: this is the constructor of the class, like the constructor function in es6 classes
• extends: extends a class from another or from an object
• implements: light checks over expected implementations and warn eventually when something is missing
• prototype
• static: define static properties in the class
• with: an array of traits, objects with properties
