Question

whenever i try to make print it out on a browser i always get the error on the header "Uncaught SyntaxError: Cannot use import statement outside a module" before asking this question i tried all solutions similar to this problem including adding "type":"module", to my json package but none seems to work,i also added the "pack" and still no print out all my scripts are properly configured i use ecma6script and the latest version of react as well,

here is my hmtl code below

    <head>
        <link rel="stylesheet" href="style.css">
    </head>
    <body>
        <div id="root"></div>
        <script src="indexx.js"></script>
    </body>
</html>```

and here is my reactcode

```import React from "react";
import ReactDom from "react-dom";

ReactDom.render(<h1>hello world</h1>, document.getElementById("root"));```

You are trying to launch not compiled sources directly from a browser. To launch a workable app you can do:

npm start - DEV server launched on localhost:3000
npm run build - PROD build, compiles the sources into the build/ folder. There you'll find compiled JS, CSS and index.html to launch.
