That’s a beautiful overview of programming language.
The following text is IMHO: to decide which programming language is the best to learn in 2018, we think how current bleeding edge standard will change the way we will develop programms in the future. Here is an example
My advice: learn a strong object oriented language (GoLang, Java, C#, C++, RUST), learn design patterns, learn how things work (e.g. how is databinding implemented) and it will be easy for you to learn another language and yeah the best advice is: just do it.
It’s a bet of the future but it’s a really good one cause with the browser the it-world has the virtual-machine for every OS which sun has always dreamed would be java-vm.
