I've been in this game since 1998 and I've seen much across the years. Back in the late 90s/early 00s, people started to get a little more sloppy due to less constraints on HW/SW (RAM, etc.). These days it seems people pay less attention to what makes a good programmer and more on the language or framework du jour. Very few people take the time to master not just a language but good habits. They flit from language to language and framework to framework. A good programmer with just a few years of experience should be able to pick up any language within reason. Having said this, going from JavaScript to C++ or Python might be a challenge if all you've ever done is front end work. Concepts like mutable/immutable, etc. can be challenging if you've never dealt with them. Constant learning, constant challenges on and off the clock, always be curious. Too many bootcamps now that don't teach anything other than getting people out the door. Notice that most of these bootcamps are for front end work. There is no way you are going to see a bootcamp cranking out a systems programmer in a few months--there is simply too much to know about how the underlying systems work together (HW/SW). A friend years ago lamented the very same thing he went through as a sysadmin with bootcamps cranking out "paper tiger" MCSEs who didn't know the first thing about running a server or setting up a domain controller or print server.
