Create simple array of strings from object

Question

I have object like this

  Names = [ 
            {
                group: 'BII',
                categories: null
            },
            {
                group: 'GVL',
                categories: []
            }
   ];

I need to create new array of string that will look like this

Groups = ['BII','GVL'];

Is there some simple solution in Angular or i need to check all properties in object?

Try this:

let Groups = Names.map((a) => a.group)

Try like this:

Working demo

if you do not want distinct, do this:

this.Names.map(x => x.group)

For distinct,

this.distinctresult = Array.from(new Set(this.allResult));

const names = [ {
            group: 'BII',
            categories: null
        },
        {
            group: 'GVL',
            categories: []
        }];

let result = names.map(({group}) => group);
console.log(result);

you can use map
