method Buffer.write
Usage in Deno
```typescript import { type Buffer } from "node:node__buffer.d.ts"; ```
Buffer.write(string: string,encoding?: BufferEncoding,): number
Writes `string` to `buf` at `offset` according to the character encoding in`encoding`. The `length` parameter is the number of bytes to write. If `buf` did
not contain enough space to fit the entire string, only part of `string` will be
written. However, partially encoded characters will not be written.
```js
import { Buffer } from 'node:buffer';
const buf = Buffer.alloc(256);
const len = buf.write('\u00bd + \u00bc = \u00be', 0);
console.log(`${len} bytes: ${buf.toString('utf8', 0, len)}`);
// Prints: 12 bytes: ½ + ¼ = ¾
const buffer = Buffer.alloc(10);
const length = buffer.write('abcd', 8);
console.log(`${length} bytes: ${buffer.toString('utf8', 8, 10)}`);
// Prints: 2 bytes : ab
```
optional
encoding: BufferEncoding = 'utf8'
The character encoding of `string`.
number
Number of bytes written.
