You could do something like this with arrow functions, it works for me on Node.

const createTask = ([name, type = 'default']) => {
 const fn = () => { ... }
 Object.defineProperty(fn, 'name', {
 value: name,
 configurable: true,
 })
 return fn
}

MDN is somewhat misleading here:

You cannot change the name of a function, this property is read-only...

To change it, you could use Object.defineProperty() though.
