What is TKO?

TKO is a Javascript web framework, and the foundation for Knockout 4.

Knockout helps you create rich, responsive, maintainable applications built on a clean underlying data model.

• Simple data-html bindings Easily associate DOM elements with model data using a concise, readable syntax, like this: <input data-bind='textInput: value'/>
• Two-way observables Data model and DOM stay in sync, updating the UI whenever the data changes.
• Computed dependencies Create chains of calculated variables dependencies.
• Templating Create reusable components and sophisticated web applications.
• Extensible Implement custom behaviours and compartmentalized code.

TKO has a comprehensive suite of tests that ensure its correct functioning and allow easy verification on different Javascript browsers and platforms.
