techniques for extracting object values and transferring them into an array

I am trying to extract the filterPillvalue and store it in an array, where the output should look like this:

mode = ['anyValue','Repsonding','Unresponsive']

My approach is as follows:

this.items = [
  {
    filterPillValue: 'anyValue',
    id: 'all-systems',
    label: 'All systems'
  },
  {
    filterPillValue: 'Responding',
    id: 'responding',
    label: 'Responding systems'
  },
  {
    filterPillValue: 'Unresponsive',
    id: 'unresponsive',
    label: 'Unresponsive systems'
  }
];

However, the following code snippet does not work in this scenario:

mode = this.items.filter(x=>x.filterPillValue);

Answer №1

Success is guaranteed.

mode = this.items.map(({filterPillValue}) => filterPillValue);

Alternatively

mode = this.items.map((element) => element.filterPillValue);

Answer №2

items = [
  {
    filterPillValue: 'anyValue',
    id: 'all-systems',
    label: 'All systems'
  },
  {
    filterPillValue: 'Responding',
    id: 'responding',
    label: 'Responding systems'
  },
  {
    filterPillValue: 'Unresponsive',
    id: 'unresponsive',
    label: 'Unresponsive systems'
  }
];

const filterValues = items.map(item=>item.filterPillValue)
console.log(filterValues)
