Script Preparation code:

Tests:

Comparing Number ===
for (let i = 0; i < table.length; i++){ const areEqual = table[i] === Number(ids[i]); }
Comparing maping ===
ids.map(Number).forEach((id) => { const areEqual = table[0] === id; });
Comparing ==
for (let i = 0; i < table.length; i++){ if (ids[i]) { const areEqual = table[i] == ids[i]; } }
Comparing no mapping ==
ids.forEach((id) => { if (id) { const areEqual = table[0] == id; } });
