{"version":"1.0","type":"rich","title":"For class","description":"This example demonstrates simple JavaScript function definitions and invocations, displaying results in separate HTML paragraphs. It shows both standard function declarations and function expressions assigned to variables, each performing multiplication. A third function, `mycalc`, sums two numbers but is never called. The page uses plain HTML elements with IDs (`demo1`, `demo2`, `demo3`) and a CSS class for large, centered text, with all logic handled in an external `learn.js` file without any external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a74808a410840549fa2fc124c49ab86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
