How can I achieve that in Javascript?
exports.functions = {
my_func: function (a) {
my_func(a);
}
}

A function expression can have an optional name after the function keyword. The scope of this name is just the function body, and allows it to be called recursively:
exports.function = {
my_func: function this_func(a) {
this_func(a);
}
}
You can also use its full name:
exports.function = {
my_func: function(a) {
exports.function.my_func(a);
}
}

in the article Bergi pointed to in the comments on the question.. that 'optional' name isn't implemented properly in some interpeters.. not sure if JScript compatibility is worth consideration though.

@BrettCaswell Only IE had the problem AFAIK - but a function expression name still works in IE. In some IE versions the scope would just bleed to a binding in the current context as well which is a side-effect that can be largely ignored.
This is not quite ok as a standard, but you can easily achieve this like:
var foo = function(a) {
foo(a);
}
exports.functions = {my_func: foo};
Your code does not work because in this case the hoisting is not done ok(well it's done ok) but not for what you need.
functions.
