&quot;full stack&quot; is definitely an overloaded term but then again I wouldn&#x27;t consider the kinds of questions OP mentions to be something only the experts would (or should) be able to answer on the basic level.<p>Things like get vs post, encoding, basic headers (like accept etc) should be familiar to anyone dealing with the client side development regardless of the tools&#x2F;frameworks.<p>And then on the backend some basic SQL, basic understanding of indexing, FKs, PKs, maybe simple inner joins is also something that someone doing anything DB-related on the backend should be familiar with (unless we&#x27;re talking someone who is only familiar with nosql dbs) regardless of the tools&#x2F;frameworks&#x2F;orm etc.
