const object = { card: { bank: { id: '123' } } };

I need to know if '123' exists in object. Any way to do that? Thanks!

You can use recursion and Array.some to search deeply for the value

const deepExists = (obj, query) =>
  Object.values(obj).some(v => typeof v === "object" ?
    deepExists(v, query) :
    v === query
  );
  
console.log(deepExists({ card: { bank: { id: "123" }}}, "123"));
