What is the difference between 'value' and 'text' bindings in KnockoutJS?

1 What are bindings in KnockoutJS?

Bindings are a way of connecting your HTML elements with your JavaScript data model. They allow you to update the view automatically when the data changes, and vice versa. For example, you can bind an input element to a JavaScript variable, and whenever the user types something in the input, the variable will be updated. Similarly, if the variable changes in the code, the input value will reflect that change.

4 What is the 'text' binding in KnockoutJS?

The 'text' binding is another common binding in KnockoutJS. It is used to bind an observable to the text content of an element, such as a span, a div, or a paragraph. It works only one way: when the observable changes, the element text is updated. For example, <span data-bind="text: name"></span> var name = ko.observable('Alice');

6 When to use 'value' and 'text' bindings in KnockoutJS?

You should use 'value' binding when you want to create a two-way data binding between an input element and an observable. This will allow you to update the data model when the user changes the input value, and update the input value when the data model changes. You should use 'text' binding when you want to create a one-way data binding between an element and an observable. This will allow you to update the element text when the data model changes, but not the other way around. You should also use 'text' binding when you want to bind an observable to an element that does not have a value attribute, such as a span or a div.
