  main: "3",
  desc: [

      id: "1",
      value: "xyz"
    },
    {
      id: "2",

If the id in desc array is unique, you could use find (doc for Array.prototype.find())

const data = {
  main: '3',
  desc: [
    {
      id: '1',
      value: 'xyz'
    },
    {
      id: '2',
      value: 'abc'
    },
    {
      id: '3',
      value: 'qwer'
    },
    {
      id: '4',
      value: 'cwer'
    }
  ]
}

const res = data.desc.find(d => d.id === data.main)

console.log(res.value)
