{"version":"1.0","type":"rich","title":"Basic Calculator Practice JS","description":"This example shows a minimal web-based calculator that performs addition, subtraction, division, and multiplication on two fixed numbers (8 and 2). The interface displays those operands alongside four operation buttons and a result area. JavaScript event handlers assigned via inline `onclick` attributes in the HTML call the corresponding functions, which directly update the text content of the `sum-el` element. The demo relies on raw DOM manipulation through `document.getElementById` and `textContent`, with styling provided by plain CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/371ec1b948134ba08cf10abaf6719a55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
