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);
