HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const arrayLength = 50;
const randomIndexForIdToFind = Math.random() * (arrayLength - 1) + 1;
const idToFind = 'foo';

const arr = [];

for (let i = 0; i < arrLength ; i++) {
  if (i === randomIndexForIdToFind) {
    arr.push({ foo: { id: idToFind }});
  } else {
    arr.push({ foo: { id: 'bar' }});
  }
}

Tests:

Array.map().includes()
arr.map(e => e.foo.id).includes(idToFind);
Array.some()
arr.some(e => e.foo.id === idToFind);
