How to return reference to array item when searching an array of objects with JavaScript?

To return reference to array item when searching an array of objects with JavaScript, we can use the JavaScript array find method.

For instance, we write:

const users = [{
  id: 1,
  name: 'name1'
}, {
  id: 2,
  name: 'name2'
}]
const user = users.find(u => {
  const {
    id,
    name
  } = u
  return id === 1 && name === 'name1'
})

We have the users array with some objects.

And we want to get the 1 with id w and name 'name1'.

To do this, we call find with a callback that returns id === 1 && name === 'name1'.

And then user will be the reference to the first entry of users.
