5    const f = await fastFile.createOverride("pattern.bin");
6
7    const buff = Buffer.from("0001020304050607", "hex");
8    for (let i=0; i<1000; i++) {
9        await f.write(buff, i*8);
10    }
11
12    await f.close();
13}
14
15async function readFile() {
16    const f = await fastFile.readExisting("pattern.bin");
17
