Check and get data from an array in JavaScript

Question

I have an object:

var Obj1 = {id: 1, name: 'Apple'}

And an array object:

var ArrObj = [ {id: 1, name: 'Apple', 'eat': 'rice}, {'id: 2', 'name': 'Banana'}]

How do I check Obj1.id in ArrObj? And I want the result to be: { id:1, name: 'Apple', 'eat':'rice'}

Answer 1

You can use Array.find():

var Obj1 = {id: 2, name: 'Banana'}
var ArrObj = [ {id: 1, name: 'Apple', 'eat': 'rice'}, {'id': 2, 'name': 'Banana'}];
var res = ArrObj.find(({id}) => id === Obj1.id );
console.log(res);

You can also use array destructuring way like:

var Obj1 = {id: 2, name: 'Banana'}
var ArrObj = [ {id: 1, name: 'Apple', 'eat': 'rice'}, {'id': 2, 'name': 'Banana'}];
var res = ArrObj.find(({id}) => id === Obj1.id);
console.log(res);

Answer 2

You could also use the filter function like this:

let result = ArrObj.filter(obj => {
  return obj.id == Obj1.id
})
