function Deno.consoleSize
consoleSize(): { columns: number; rows: number; }
Gets the size of the console as columns/rows.
```ts
const { columns, rows } = Deno.consoleSize();
```
This returns the size of the console window as reported by the operating
system. It's not a reflection of how many characters will fit within the
console window, but can be used as part of that calculation.
{ columns: number; rows: number; }
