Hello there,

I have a problem to update all objects in a deep array.

My structure of elements is:

{
   "name":"",
   "category":"",
   "notes":"",
   "sections":[
      {
         "name":"Workout",
         "exercises":[
            {
               "sets":[
                  {
                     "value":5,
                     "workload":100,
                     "workload_type":"kg",
                     "timer":120,
                     "repetitions":[
                        5, 3
                     ]
                  },
                  {
                     "value":5,
                     "workload":100,
                     "workload_type":"kg",
                     "timer":120,
                     "repetitions":[
                        5, 2
                     ]
                  }
               ],
            }
         ]
      }
   ]
}

I want to add a repetition in all repetitions keys in each set, so i do:

state.updateIn(
          ['sections', index_section, 'exercises', index_exercise, 'sets'],
          sets => sets.map(s => s.update('repetitions', repetitions => repetitions = 5))
        )

But i have an error: s.update is not a function. Variable s is not an immutable object but i don't know why.
