Question

This is probably something stupid, but I have code like this:

var f = functionWrapper();
f.apply(this, []);

function functionWrapper() {
    return new function () {
        console.log("Called function");
    }
}

Why does it crash and give the following error:

Uncaught TypeError: Object [object Object] has no method 'apply' test.html:28(anonymous function)

Answer 1

Change this:

    return new function () {

(which immediately invokes the function as a constructor, and returns the constructed object) to this:

    return function () {

(which returns the function itself).
