+/**
+ * `Buffer` objects are used to represent a fixed-length sequence of bytes. Many
+ * Node.js APIs support `Buffer`s.
+ *
+ * The `Buffer` class is a subclass of JavaScript's [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) class and
+ * extends it with methods that cover additional use cases. Node.js APIs accept
+ * plain [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) s wherever `Buffer`s are supported as well.
+ *
+ * While the `Buffer` class is available within the global scope, it is still
+ * recommended to explicitly reference it via an import or require statement.
+ *
+ * ```js
+ * import { Buffer } from 'node:buffer';
+ *
+ * // Creates a zero-filled Buffer of length 10.
+ * const buf1 = Buffer.alloc(10);
+ *
+ * // Creates a Buffer of length 10,
+ * // filled with bytes which all have the value `1`.
+ * const buf2 = Buffer.alloc(10, 1);
+ *
+ * // Creates an uninitialized buffer of length 10.
+ * // This is faster than calling Buffer.alloc() but the returned
+ * // Buffer instance might contain old data that needs to be
+ * // overwritten using fill(), write(), or other functions that fill the Buffer's
+ * // contents.
+ * const buf3 = Buffer.allocUnsafe(10);
+ *
+ * // Creates a Buffer containing the bytes [1, 2, 3].
+ * const buf4 = Buffer.from([1, 2, 3]);
+ *
+ * // Creates a Buffer containing the bytes [1, 1, 1, 1] – the entries
+ * // are all truncated using `(value & 255)` to fit into the range 0–255.
+ * const buf5 = Buffer.from([257, 257.5, -255, '1']);
+ *
+ * // Creates a Buffer containing the UTF-8-encoded bytes for the string 'tést':
+ * // [0x74, 0xc3, 0xa9, 0x73, 0x74] (in hexadecimal notation)
+ * // [116, 195, 169, 115, 116] (in decimal notation)
+ * const buf6 = Buffer.from('tést');
+ *
+ * // Creates a Buffer containing the Latin-1 bytes [0x74, 0xe9, 0x73, 0x74].
+ * const buf7 = Buffer.from('tést', 'latin1');
+ * ```
