react renders object object code example

Example: object.entries render component react

{
    areas: ['areaid_0', 'areaid_1', 'areaid_2'],
    areaDetails: {
        'areaid_0': {title: 'Some title', isSelected: false},
        'areaid_1': {title: 'Some title', isSelected: false},
        'areaid_2': {title: 'Some title', isSelected: false}
    }
}
When it comes to rendering you can do like,

this.state.areas.map(x => {
  const areaDetail = this.state.areaDetails[x];
  <Component key={x} {...areaDetail}... />
})
When you wants to update any object, you can do like,

this.state.areaDetails[x].isSelected = true;
