Use Javascript to check if JSON object contain value [duplicate]

const arr = [
  {
    id: 19,
    cost: 400,
    name: 'Arkansas',
    height: 198,
    weight: 35 
  }, 
  {
    id: 21,
    cost: 250,
    name: 'Blofeld',
    height: 216,
    weight: 54 
  }, 
  {
    id: 38,
    cost: 450,
    name: 'Gollum',
    height: 147,
    weight: 22 
  }
];

console.log(arr.some(item => item.name === 'Blofeld'));
console.log(arr.some(item => item.name === 'Blofeld2'));

// search for object using lodash
const objToFind1 = {
  id: 21,
  cost: 250,
  name: 'Blofeld',
  height: 216,
  weight: 54 
};
const objToFind2 = {
  id: 211,
  cost: 250,
  name: 'Blofeld',
  height: 216,
  weight: 54 
};
console.log(arr.some(item => _.isEqual(item, objToFind1)));
console.log(arr.some(item => _.isEqual(item, objToFind2)));
