Script Preparation code:

const uint8array = new Uint8Array(81);

for(let i = 0; i < 81; i++) {
    uint8array[i] = Math.floor(Math.random() * 2);
}

Tests:

slice()
for (let i; i < 1000; i++) { const copy = uint8array.slice(); r = Math.floor(Math.random() * 81); copy[r] ^= 1; }
spread
for (let i; i < 1000; i++) { const copy = [...uint8array]; r = Math.floor(Math.random() * 81); copy[r] ^= 1; }
from()
for (let i; i < 1000; i++) { const copy = TypedArray.from(uint8array); r = Math.floor(Math.random() * 81); copy[r] ^= 1; }
with()
for (let i; i < 1000; i++) { r = Math.floor(Math.random() * 81); const copy = uint8array.with(r, uint8array[r] ^ 1); }
