To pass variables from a Handlebars file to a JavaScript file (like script.js), you can follow these steps:

1. Declare the Variables in the Handlebars Template: In your Handlebars template file (let's say it's template. has), declare the variables you want to pass to script.js. For example:

<script>
   var sections = {{{sections}}}; // Use triple braces to avoid HTML escaping
   var categories = {{{categories}}};
</script>

Here, sections and categories are assumed to be JavaScript objects or arrays.

2. Render the Template with Data: When rendering your Handlebars template, pass the necessary data:

const templateData = {
   sections: JSON.stringify([...]), // Assuming sections is an array of objects
   categories: JSON.stringify({...}) // Assuming categories is an object
};
const template = Handlebars.compile(templateSource);
const html = template(templateData);
document.getElementById('container').innerHTML = html;

Ensure that you use JSON.stringify() to convert JavaScript objects or arrays to strings.

3. Access the Variables in script.js: Now, in your script.js file, you can access these variables:

console.log(sections); // Output the sections array/object
console.log(categories); // Output the categories array/object

By following these steps, you'll be able to pass variables from a Handlebars template to a JavaScript file. Remember, it's important to ensure that the variables are properly formatted and passed as needed, especially if they contain complex data structures like arrays or objects.
