- let instance = module.instantiate(&imports)?;
+ let instance = Instance::new(&module, &import_object)?;
```

```diff
let import_object = imports! {
    "env" => {
-         "sum" => func!(sum),
+         "sum" => Function::new_native(&store, sum),

```javascript
document.addEventListener('DOMContentLoaded', function() {
    const contentSection = document.getElementById('content');

    fetch('content.html')
        .then(response => {
            if (!response.ok) {
                throw new Error('Network response was not ok');
            }
            return response.text();
        })
        .then(html => {
            contentSection.innerHTML = html;
        })
        .catch(error => {
            console.error('Error loading content:', error);
