Yes! Web languages!
They are important because maybe someday you will need to scrape the web, use JSON flies for your analysis, deploy your model into a REST service or something like that. If you don’t know what I meant before is ok, this is not a core part of your job. But it won’t hurt to understand a little bit of how the web is structured, the main languages it uses and how it works. As I said before, a Data Scientist it’s not someone who knows it all, or will solve every problem in a company, but you should know a little about topics that will be more and more important in the present and future, and the web is one of them.
This path won’t make you a Web Developer, is only to get some intuition on the different parts of a web page, how to understand its underlying structure and how to play with it.
