You can bind an array of objects from a promise in knockout.js using the foreach binding. Here's an example of how you can do this:

  1. Fetch data from a promise:
1
2
3
4
5
// Assume that fetchData() is a function that returns a promise that resolves to an array of objects
fetchData().then(data => {
    // bind the data to your view model
    viewModel.items(data);
});


  1. Create a view model in knockout.js:
1
2
3
4
const viewModel = {
    items: ko.observableArray([]),
};
ko.applyBindings(viewModel);


  1. Bind the array of objects in your HTML using the foreach binding:
1
2
3
4
5
6
7
<ul data-bind="foreach: items">
    <li>
        <span data-bind="text: name"></span>
        <span data-bind="text: age"></span>
        <!-- Add more bindings for other properties of the object -->
    </li>
</ul>


By following these steps, you can bind an array of objects from a promise in knockout.js and display the data in your view.
