with. **Default:** `0`.

* `encoding` {string} If `fill` is a string, this is its encoding.

**Default:** `'utf8'`.

Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the

`Buffer` will be zero-filled.

* `size` {integer} The desired length of the new `Buffer`.

Allocates a new `Buffer` of `size` bytes. If `size` is larger than

[`buffer.constants.MAX_LENGTH`][] or smaller than 0, [`ERR_OUT_OF_RANGE`][]

* `size` {integer} The desired length of the new `Buffer`.

Allocates a new `Buffer` of `size` bytes. If `size` is larger than

[`buffer.constants.MAX_LENGTH`][] or smaller than 0, [`ERR_OUT_OF_RANGE`][]

* `offset` {integer} The starting offset within `view`. **Default:**: `0`.

* `length` {integer} The number of elements from `view` to copy.

**Default:** `view.length - offset`.

Copies the underlying memory of `view` into a new `Buffer`.

* `array` {integer\[]}

Allocates a new `Buffer` using an `array` of bytes in the range `0` – `255`.

Array entries outside that range will be truncated to fit into it.

* `byteOffset` {integer} Index of first byte to expose. **Default:** `0`.

* `length` {integer} Number of bytes to expose.

**Default:** `arrayBuffer.byteLength - byteOffset`.

This creates a view of the [`ArrayBuffer`][] without copying the underlying

memory. For example, when passed a reference to the `.buffer` property of a

* `buffer` {Buffer|Uint8Array} An existing `Buffer` or [`Uint8Array`][] from

which to copy data.

Copies the passed `buffer` data onto a new `Buffer` instance.

* `object` {Object} An object supporting `Symbol.toPrimitive` or `valueOf()`.

* `offsetOrEncoding` {integer|string} A byte-offset or encoding.

* `length` {integer} A length.

For objects whose `valueOf()` function returns a value not strictly equal to

`object`, returns `Buffer.from(object.valueOf(), offsetOrEncoding, length)`.

* `string` {string} A string to encode.

* `encoding` {string} The encoding of `string`. **Default:** `'utf8'`.

Creates a new `Buffer` containing `string`. The `encoding` parameter identifies

the character encoding to be used when converting `string` into bytes.
