Passing class method as parameter in Typescript

This doesn’t compile-time check that the function came from a Foo, but does the rest:

class Foo {
    public somefunc() {
        // do some
    }
    public anyfunc() {
        // do any
    }
}

function bar(obj: Foo ,func: () => void) {
    func.call(obj);
}

bar(new Foo(), Foo.prototype.somefunc);  // do some
bar(new Foo(), Foo.prototype.anyfunc);  // do any
