Wanting to use same tools for backend and frontend is one of the reasons. IMO, there's only one gain to SSR and that's the one you can instantly feel when using the app - it's that the page load seems faster. That's it. Added benefit is that your app/site can be indexed by search engines since there's no XHR going on that has to fetch additional data for that first request. Using the argument that dev does not have to learn something else in the technology world - I never liked that reasoning. We, developers, use tools. Languages are tools. I, and many that I worked with, learn multiple langues over the time, whether they want to or not. I don't know a developer that doesn't know, at least, how to use CSS next to using JavaScript. That's simply what our area of work requires. If one refuses, doesn't want to or can't learn an additional tool - well, is that a developer or code plumber?
