{"version":"1.0","type":"rich","title":"자바스크립트공부","description":"This example demonstrates basic JavaScript and CSS integration within a simple HTML page. It writes a red-colored message and a user’s age directly into the document using `document.write`, then triggers an `alert` displaying the age variable. The code uses core DOM methods like `document.write` and the global `alert` function, with no external libraries. The page’s embedded script and external `age.js` file highlight foundational scripting patterns in a plain HTML structure, emphasizing how JavaScript can manipulate page content and interact with the user.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e23e886bf0fb46319ad97f5de78bb854?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
