Yes, you can write JavaScript in Pug in templates to dynamically generate content. Pug supports three types of JavaScript code: Buffered Code: This is the code that will be displayed as a result. Unbuffered Code: This is code that will not be displayed in the HTML result. You can use this method to perform logical operations or initialise variables. Unescaped Buffered Code: If you use !=, the JavaScript code will be displayed without escaping, which allows you to embed unformatted HTML in the result: p!= ‘Hello’Here Hello will be displayed as unformatted HTML.
