How to send whatsapp message via Javascript

Question

Hi I would like to know if there is something to send a whatsapp message using javascript or something I was searching but I did not find any new post. This is not for any special purpose. I found this but it only works if you have whatsapp web. I was thinking on clicking on a link to send a default message to a default number

<a href="https://api.whatsapp.com/send?phone=1111111111">Send Message</a>

Just make use of this function in web browser to get it running as you want.

Note: You need to run the code manually through browser console with an opened conversation in WhatsApp (web version).

function sendMessage (message) {
  window.InputEvent = window.Event || window.InputEvent;

  var event = new InputEvent('input', {
    bubbles: true
  });

  var textbox = document.querySelector('div._2S1VP');

  textbox.textContent = message;
  textbox.dispatchEvent(event);

  document.querySelector("button._35EW6").click();
}

Important: If you're trying to send a message directly from URL (i.e using API), you cant. Its impossible to send WhatsApp messages without user interaction.
