Is it possible to put a function as a key in an ES6 computed key?

I'm reviewing this piece of code in the redux-connect library and I'm wondering if it is possible to put a function as a key in a computed key in ES6. How does it work and how is javascript interpreted?

export const reducer = handleActions({
  [beginGlobalLoad]: state => ({
   ...state,
  loaded: false,
}),

[endGlobalLoad]: state => ({
  ...state,
  loaded: true,
})
....
}

with beginGlobalLoad is the function created by

export const beginGlobalLoad = createAction('@redux-conn/BEGIN_GLOBAL_LOAD');

I read the concept of dynamic computed key, but it doesn't say anything about using a function as a key for a property.

Thank you very much for your response

Not. Property keys must be either strings or characters. If you use a function, it will collapse like any other object, and this is usually not what you want.

However, the createAction

docs indicates that



createAction

also returns its type when used as a type in handleAction

or handleActions

.

which they achieve rewritingtoString

.
