Whats the Default projection when creating a map in JavaScript? WHATS the Code number?

I am working on a piece of code that is exporting a shapefile and it should be coming out with the projection of the map...need to do some testing...

Is it Web Mercator WGS 84 ? If so whats the number for that?

Jay,

I assume you mean what is the WKID. If you are using esri basemaps it would be 102100 or 3857 (thy are basically the same)

The default spatial reference is dictated by the map service used in the map. if you are using any tiled map service then map spatial reference will be that of the tile map service.

If you are using dynamic service it'll be first map service's spatial reference.
