var isPresent = this.productArray.some( (el) => { el.id === 2} ); I saw this code here. it returns boolean, i want to get the other field. not just to identify if it exist. – C.E James Sep 21 '18 at 14:25

You need either `Array.propotype.filter` or new `Array.prototype.find`. – Yury Tarabanko Sep 21 '18 at 14:26

You can use Array.propotype.filter
var list=[
{id: 1, name: 'foo'},
{id: 2, name: 'bar'},
{id: 3, name: 'test'}
]
const result = list.filter(data => data.id == 2);
console.log(result);
