If I do something like this it seems to work:
function a() { ... }
a.desc = "Description of a";
But can I break anything by doing that? Is there a better way?

1What are you trying to achieve? Why do you need a function instead of just declaring an object? – webnoob Jan 27 '18 at 12:41

From MDN:
In JavaScript, functions are first-class objects, because they can have properties and methods just like any other object. What distinguishes them from other objects is that functions can be called. In brief, they are Function objects.
Since functions are first-class objects, there is no way of breaking down anything by adding properties to them.

What about property name clashes? If "desc" becomes a standard property name what will happen? How do I check for it? – Leo Jan 27 '18 at 13:09
