There are tools that do that sort of thing but they are very advanced and cost millions and are not part of EasyEDA.  Usually they are part of IC design packages but can be applied to discretes as well.

The Design Manager in the left hand panel will show you if any nets or pins have only one connection to them and you can go through all the nets to check that they are connected correctly but you have to do that by hand. At some point in the future the DRC may be upgraded to check for outputs connected to other outputs or to power or power to power connections but that is often not as useful as it might seem and can often give false alarms.
