testTS.ts

import { ConnectionState, MessageUpsertType, proto } from "@whiskeysockets/baileys";

import { default as WabotSocket, useMultiFileAuthState } from "@whiskeysockets/baileys";

(async function connect() {

  const bot = WabotSocket({
    browser: ["Chrome (Linux)", "", ""],
    auth: state,
    printQRInTerminal: true,
    defaultQueryTimeoutMs: undefined,
    syncFullHistory: false,
  });

  bot.ev.on("messages.upsert", async function (
    {
      messages,
    }: {
      messages: proto.IWebMessageInfo[];
      type: MessageUpsertType;
    }
  ) {
    const m = messages[0];
    if (!m.message) return;
    const messageType = Object.keys(m.message);
    console.log(m)
    if (!m.key.remoteJid?.endsWith("@g.us")) return;
    if (!m.key.fromMe) return;
    if (!messageType.includes("audioMessage")) return;

    await bot.sendMessage(m.key.remoteJid as string, { text: "hola mundo" }, { quoted: m });
  })

  bot.ev.on("connection.update", (c: Partial<ConnectionState>) => {
    const { connection, lastDisconnect } = c;
    if (lastDisconnect == undefined) return;
    if (connection === "close") {
      console.log(lastDisconnect);
      connect();
    }
    if (connection === "open"){
        console.log(bot?.user?.id.split(":")[0])
    }
  });
  bot.ev.on("creds.update", saveCreds)
})();

What is the expected behavior?

The script initiate the connections with the service and return a QR code after that the app finish their connection and run as expected

bun run ./src/testTS.ts

Minimum repro:

var a = function () {};
a();
function a() {}

Due to hoisting, transpiler outputs:

let a = function() {
};
var a = function() {
};
a();

[paperdave]

ive seen this before.

this is very similar but not the exact same to #5732, where the minimum reproduction is:

function A() {}
var A;
