You can use Array#find function and pass a condition into it like

arr.find(item => item.id === 1)

Example

const users = [
  {id: 1, name: 'A'},
  {id: 2, name: 'B'},
];

const user = users.find(item => item.id === 1);

console.log(user);

var abc = arr.find(item => item.id === 2053) abc "Undefined" – Faisal Nov 28 '17 at 07:38
Your property name is `Id` not `id`, with capital letter – Suren Srapyan Nov 28 '17 at 07:39
var abc = arr.find(item => item.id == 2053) "==" works but why? – Faisal Nov 28 '17 at 07:46
Because `==` will try to cast your id's into boolean value, and if the number is not `0`, it will be casted into `true` so actually you use `true == true`. But this is logically wrong. Use `===` instead of `==` and proper property names – Suren Srapyan Nov 28 '17 at 07:48
var abc = dataArr.find(item => item.Id == elem); ** typeCast elem ??? ** – Faisal Nov 28 '17 at 07:50
Man, use `===` this syntax and `Id` property to get the correct results. Anything else will give you logically wrong values – Suren Srapyan Nov 28 '17 at 07:51

Use find()

var item = yourArray.find(item => item.id === 2053);

DEMO

const yourArray = [
  {Id: 2053, title: 'sass'},
  {Id: 2054, title: 'sdss'},
];
const found = yourArray.find(item => item.Id ===2053);
console.log(found);

Yo can also use var requiredItem = array.filter(i => i.id == 2054)

Example

var arrayNew = [
  {id: 2053, name: 'sxsxs'},
  {id: 2054, name: 'sss'}  
];

var requiredItem = arrayNew.filter(i => i.id == 2054);

console.log(requiredItem);

let obj = [{
 "id" : 1,
 "Title" : "Hi"
},{
"id" : 11,
 "Title" : "Hello"
}]

function filterById(ids) {
  return  obj.filter((obj) => {return obj.id == ids})  
}

console.log(filterById(11))
