It seems there might be a slight misunderstanding. There is no specific “YUI programming language”. YUI (Yahoo! User Interface) Library is actually a collection of JavaScript tools and techniques designed to simplify web development. It doesn’t have its own syntax separate from JavaScript.
However, if you want to write “Hello World!” in JavaScript, which is often used alongside the YUI Library, it would look like this:
javascript
console.log("Hello World!");
