Is there any point in learning new (very young) tools and programming languages ​​and what are their prospects?

Question

Dart

Learning one language does not make sense today. Technology stacks are in demand. As a rule, a "pure" language is also not studied, and after a certain level of knowledge, further work is already underway with advanced tools and libraries. New languages
​​are constantly appearing , like GO, Dart , Phyton, Ruby on Rails are gaining popularity (although they are not in demand in Russian companies). Is it worth it now to start studying and does it make sense? The issue of wasted time worries the most - it will be a shame if in the future you will not be in demand on the market. Now I have basic knowledge of php+js+html+css. Options for working both for yourself (freelance) and in the company are being considered. I would be grateful for advice.

Answer 1

As rightly noted above, Python and Ruby have been around for 20+ years, so they gained popularity a long time ago.
Go, Dart, Rust, D, etc are interesting to study in order to broaden one's horizons, but they are not suitable for "production": in 5 years you will not acquire an extensive community, which means no choice in terms of libraries or professional staff. Of course, there may be separate projects professing these languages, but such a minority.
Recently, many jump around JavaScript: first it was transferred to the server (in fact, it was done long before Node.JS, but did not take off), and then they began to use it almost everywhere (in win8, for example, or PhoneGap). But JS was lucky to have quite a large community at the height of this hype, and that's why it started.
Choose something from Python, Ruby, JS and understand it (not so much in the language itself, but in its ecosystem, i.e. libraries, frameworks and patterns). It will be necessary - you will understand another language with its ecosystem. The ideas are the same everywhere, only syntactic sugar differs.
