Alpinejs and arrow functions

Hi!

I am using alpinejs to sometimes code directly on html when things are small and simple. I noticed that if I use an arrow function the console gives me an error (async function) and stops executing code, but it works if I use a regular function.

I think it’s something in the webpack config (I am importing alpinejs as vendor).

Of course, arrow functions work as expected when inside the js or a script tag.

I didn’t find anything on the alpinejs or webpack github though :frowning:

Post your code

Sure

in the HTML:

<div x-data="{
  init() {
    const array = [4,3,2,1];
    array.forEach((item,index) => {
      array[index] = array[array.length - index - 1];
      array[array.length - index - 1] = item;
    });
    console.log(array);
  }
}"></div>

in app.js

import Alpine from 'alpinejs';

in package.json

  "dependencies": {
    "alpinejs": "^3.10.5",
  }

And the error is:

Uncaught SyntaxError: Invalid or unexpected token
