Choose between version 3.33 and 4.16

Version 4.x of the ArcGIS API for JavaScript includes almost all capabilities that are part of 3.x along with many new innovations that are exclusive to 4.x; for example 3D visualization, map rotation, and deeper ArcGIS Enterprise and ArcGIS Online integration. While not all 3.x capabilities are included in 4.x, each release adds more functionality until it not only matches 3.x but far exceeds it. Developers should consider their app requirements and evaluate whether the current 4.x or 3.x release has the desired capabilities. For example:

  • Does the app need 3D visualization? If so, use 4.x.
  • Do you need a particular functionality from 3.x that's not yet available in 4.x such as analysis widgets or WFS? If so, use 3.x.
  • Are you working with very large feature layers? If so, use 4.x.
