Developer essentials
Since SharePoint 2019 is a big change from all other versions of SharePoint, there are things you need to know to move forward as a developer. As stated, we have seen so many changes over the years, especially between 2007, 2010, and 2013. These versions brought big functionality changes, which then brought development changes and changes to out-of-the-box functionality.
The same goes for this version; as you will see in this chapter, SharePoint 2019 is bringing the cloud SharePoint Online service to an on-premises environment. Although it's not patched and updated to the standard of the server used in the cloud, we do see most features available for developers. Admins do not have the same configuration features in the on-premises servers that support SharePoint Online. These features will probably never surface in an on-premises build. If they do, these features would be a great addition to environments that need administrative support.
The good thing...
