There is more to it. Even on different platforms there are a lot of shared APIs and principles. But yes, you still need a further understanding of the context you are now using the language in. Not to mention that you likely still need to do some further learning. But, overall I'd say it still makes it significantly easier for someone to make a switch. Even more so given the current eco system where a front-end dev likely already has node.js installed, is somewhat familiar with npm, etc. Even if we just stick to the syntax, just not having to worry about one such aspect when switching context overall shouldn't be understated as a benefit imho.
