copied!<p>No, it's impossible without reassigning a [[prototype]] to a function object. IE does neither support the nonstandard <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/proto" rel="nofollow"><code>__proto__</code> property</a> nor the ES6 method <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/setPrototypeOf" rel="nofollow"><code>Object.setPrototypeOf</code></a>.</p> <p>The only custom callable objects are functions which you create with function expressions/declarations or the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function" rel="nofollow"><code>Function</code> constructor</a>. However, all of these methods will create function objects which have their [[prototype]] <a href="http://es5.github.io/#x13.2" rel="nofollow">set to</a> the builtin <a href="http://es5.github.io/#x15.3.4" rel="nofollow"><code>Function.prototype</code> object</a>.</p> <hr> <blockquote> <p>F will be used as a constructor (in a compiled to javascript language). But the code is going to be more complex. The core idea is that there will be one more line <code>F.prototype = F</code> after that, so all objects created from F will see the attributes of their class; i.e. <code>f = new F(); F.foo = 123; print(f.foo);</code></p> </blockquote> <p>Don't do that. While F is a (constructor) function, your instances are not, so there's no reason to let them inherit from it. Just comile your class attributes to <code>F.prototype.foo = 123;</code>. Or compile any accesses to static properties (where "instances see class attributes") to use the <code>F</code> object instead, so <code>print(F.foo)</code>.</p>
