Enumerate non-enumerated NFTs in web3.js

Question

I want to call the ownerOf() function on all of the NFT's in a contract. If the address matches the website user address I want to add the tokenID to an array so I can eventually display all nft's owned by the user.

The code below almost works, I think it breaks when ownerOf() returns an error. Also is calling ownerOf() 1000+ times going to timeout or something?

for (let i = 0; i < 1000; i++) { if(await contract.methods.ownerOf(i).call({ from: window.userAddress }) ===window.userAddress{ list.push(i); }; } alert(Owned by this address ${list});

You should use an API like Moralis which is designed to easily retrieve information like this. I had the same problem. This was the exact API call I needed:
