Take the method `buf.readIntLE(offset, byteLength)`:\n\n```js\nBuffer.prototype.readIntLE.call(Uint8Array.of(1, 0, 0, 0, 0), 0, 3);\n// 1\n\nBuffer.prototype.readIntLE.call(Uint8Array.of(1, 0, 0, 0, 0), 0, 4) \n// Uncaught TypeError: this.readInt32LE is not a function\n//    at Uint8Array.readIntLE (node:internal/buffer:349:17)\n```\n\nDepending on the `byteLength` given, the method will respond correctly or throw a `TypeError` if it happens to be written using a code path that uses an internal method found only on the Buffer prototype. \n\nAs a library author, I would also like to easily accept Uint8Arrays wherever Buffers are accepted and not spend time converting the input to a Buffer instance to get useful byte utilities to work on both possible inputs.\n\n### What is the feature you are proposing to solve the problem?\n\nI propose to make the few code paths that rely on internal methods invoke those functions in a way that doesn't require them to be defined on the currently bound `this` value's prototype.\n\nFor example:\n```js\nreturn this.readInt32LE(offset);\n```\nbecomes\n```js\nreturn FunctionPrototypeCall(readInt32LE, this, offset);\n```\n\nAnd add coverage for existing and future methods to maintain this contract.\n\n\n### What alternatives have you considered?\n\nA couple but less desirable alternatives:\n- Convert input by invoking `Buffer.from(ArrayBuffer, byteOffset, byteLength)`\n- Reimplement the methods in library to work with either input","author":{"url":"https://github.com/nbbeeken","@type":"Person","name":"nbbeeken"},"datePublished":"2025-01-13T02:19:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/56577/node/issues/56577"}
