{"version":"1.0","type":"rich","title":"Implementation of Native JavaScript Methods (forEach, Map, Filter, Reduce, Every, Some)","description":"This example shows how to reimplement six core JavaScript array methods—forEach, map, filter, reduce, every, and some—using native loops and callbacks. The code defines custom prototypes like `Array.prototype.myEach` and `Array.prototype.myMap`, then tests each with sample arrays and console output. It demonstrates the underlying logic of these standard APIs, including handling initial values in `myReduce` and context binding in `myFilter`. The implementation relies solely on plain JavaScript syntax, with no external libraries, and uses console logging to display results.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c5c3c35da5ffd9ce13519be9492a175b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
