i cant add a shape file to the map

can any one tell me what is error here

it not display any error but also it dose not add file to the map

this is my code"

Have you looked at this sample: Add shapefile | ArcGIS API for JavaScript

You can download the source as a zip file and extend it to meet your needs.

But the link you provided is for legacy version 3.46, which is going to retire on July 1, 2024. Is that not available for newer version which is 4.29?
Or ESRI has removed shape file functionality in newer version?
