Yes there is no harm in making sure that you are prepared and have a varied skillset. Speaking from experience front-end developers these days need to have some knowledge of the back-end. And even though the MERN stack might be popular among developers it is quite common for companies to expect those developers to know SQL.
So you see it makes sense to know MongoDB and PostgreSQL or even another SQL database like MySQL. And in regards to Express and Nest. Express is more popular but these days TypeScript has grown a lot and Nest is one of the most ideal frameworks because it supports TypeScript out of the box whereas Express requires a setup process to get TypeScript working.
So thats why I included all of those languages and technologies in one article. To give the user an overview and give them the knowledge to be successful.
