It says,
Use Object.{keys,values,entries}, and iterate over the resulting
array.
So you could do something like this to get the object keys as an array and then loop through the keys to make necessary changes.
currentValues= {hey:1212, git:1212, nmo:12121}
Object.keys(currentValues).forEach(function(key) {
yield put(setCurrentValue(key, currentValues[key]));
})
