Tests:

using filter
const allParticipants = Object.keys(participants).filter((id) => id !== currentID); const allParticipants2 = Object.keys(participants).filter((id) => id !== noCurrentID);
using check before filter
if (participants[currentID]) { const allParticipants = Object.keys(participants).filter((id) => id !== currentID); } if (participants[noCurrentID]) { const allParticipants = Object.keys(participants).filter((id) => id !== noCurrentID); }
checking amount and if
const coef = participants[currentID] ? 1 : 0; const amountOfParticipants = Object.keys(participants).length - coef; if (amountOfParticipants === 1) {} else {} const coef2 = participants[noCurrentID] ? 1 : 0; const amountOfParticipants2 = Object.keys(participants).length - coef2; if (amountOfParticipants2 === 1) {} else {}

A complex benchmarking scenario!

It appears that we have a JSON object with two arrays: `participants` and some additional metadata.

The `participants` array has multiple entries, each with an ID and a corresponding value. We're interested in a specific entry where the ID is "51".

We also have three individual test cases:

1. **"using filter"`**: This test case uses the `filter()` method to exclude the current ID from all participants.
2. **"using check before filter"`**: This test case checks if the current ID or another ID (200) exists in the `participants` array, and then filters out those IDs using the same approach as above.
3. **"checking amount and if"`**: This test case uses conditional statements to determine if there is only one participant left after filtering.

The latest benchmark results show three different browsers/clients running these tests at varying rates:

1. **"checking amount and if"`** ( Opera 109, Windows, Desktop): 338498.125 executions per second
2. **"using check before filter"`** (Opera 109, Windows, Desktop): 223954.234375 executions per second
3. **"using filter"`** (Opera 109, Windows, Desktop): 116060.4453125 executions per second
