Small helper to assist you with finding/filtering elements in an array by a specific key.

Example

const by = require('find-by')

const list = [
  { title: 'A New Hope', episode: 'IV' },
  { title: 'The Empire Strikes Back', episode: 'V' },
  { title: 'Return of the Jedi', episode: 'VI' }

const list = [
  { id: 15, name: 'Foo' },
  { id: 42, name: 'Bar' },
  { id: 10, name: 'Baz' }
]

console.log(list.find(by.id(42)).name)
// => Bar
