in IE 11 I can't update my store. First time it add data, but next time, when I try update it not working.
I try use polyfill
import Immutable from 'immutable'
const objectAssign = require('object-assign');
const initialUserState =
{
}
;
const BackupReducer = function(state = initialUserState, action) {
//console.log('actiondata in reducer:' + action.data + action.type);
switch(action.type) {
case 'GET_BACK_LIST':
return objectAssign({}, state, { backups: action.data });
break;
but it not helps: in console I see:
