Question

Suppose there is an Array that has some objects like below

[{name:"Bruce wayne" age:42 DOA:true},{name: "Dick grayson" age:28 DOA:true},{name:"Jason todd" age:24 DOA:false}]

and I want to get a new Array with Objects which DOA is true (bruce and dick).

Is there any good API or something to do this?

You can simply use Array.prototype.filter:

const data = [{
  name: "Bruce wayne",
  age: 42,
  DOA: true
}, {
  name: "Dick grayson",
  age: 28,
  DOA: true
}, {
  name: "Jason todd",
  age: 24,
  DOA: false
}];

console.log(data.filter(obj => obj.DOA));

Mind that your JSON was also invalid.

This is an ***often*** repeated duplicate question. We close those in favor of the previous versions so that we don't have a million different answers to the same question. – T.J. Crowder Jul 29 '21 at 16:07
oh then, what if I want to get objects which DOA is false? – geo Jul 29 '21 at 16:10
@user15508209 `obj.DOA === false` – VLAZ Jul 29 '21 at 16:12
@user15508209 - Or `obj => !obj.DOA` assuming you won't have other falsy values like `0` or `""`. – T.J. Crowder Jul 29 '21 at 16:16
