method Deno.Conn.write
Conn.write(p: Uint8Array): Promise<number>
Write the contents of the array buffer (`p`) to the connection.
Resolves to the number of bytes written.
**It is not guaranteed that the full buffer will be written in a single
call.**
```ts
const conn = await Deno.connect({ hostname: "example.com", port: 80 });
const encoder = new TextEncoder();
const data = encoder.encode("Hello world");
const bytesWritten = await conn.write(data); // 11
```
Promise<number>
