method Buffer.writeUInt16LE

Usage in Deno

```typescript import { type Buffer } from "node:node__buffer.d.ts"; ```



Buffer.writeUInt16LE(value: number,
offset?: number,
): number

Writes `value` to `buf` at the specified `offset` as little-endian. The `value` must be a valid unsigned 16-bit integer. Behavior is undefined when `value` is anything other than an unsigned 16-bit integer. This function is also available under the `writeUint16LE` alias. ```js import { Buffer } from 'node:buffer'; const buf = Buffer.allocUnsafe(4); buf.writeUInt16LE(0xdead, 0); buf.writeUInt16LE(0xbeef, 2); console.log(buf); // Prints: ```

Parameters



value: number

Number to be written to `buf`.

optional



offset: number = 0

Number of bytes to skip before starting to write. Must satisfy `0 <= offset <= buf.length - 2`.

Return Type

number

`offset` plus the number of bytes written.
