Javascript – send message every "x" seconds

I would like to send messages every 5 seconds on differents numbers with this code:

const send_message = ["34123456789","34123456789","34123456789"];

client.on("ready", () => {
   console.log("Client is ready!");
   send_message.map((value) => {
     const chatId = value + "@c.us";
     const message = 'This is a test message';

     client.sendMessage(chatId, message);
   });
});

Where or how can I add this code to create a correct bucle?

await sleep(5000);

    use a for…of loop instead and make the client.on callback async

    Something like

    const send_message = ["34123456789", "34123456789", "34123456789"];

client.on("ready", async () => {
  console.log("Client is ready!");

  for (value of send_message) {
    const chatId = value + "@c.us";
    const message = 'This is a test message';
    client.sendMessage(chatId, message);
    await sleep(5000);
  }
});

    You can use await only in an async context. So you can do like this for instance, using for .. of instead of map

    client.on("ready", async () => {
  for (let value of send_message) {
    const chatId = value + "@c.us";
    const message = 'This is a test message';    
    client.sendMessage(chatId, message);
    await sleep(5000);
  }
})

    BTW since node 16 you don’t need to create your own sleep (or similar) method anymore. You can use setTimeout from the timers/promises module
