Ask HN: Learn another programming language

3 points·aaossa··2 comments

Hi HN. I want to know how do you learn more programming languages. When I want to learn a new one I only find really basic pages, with stuff like int, strings, etc.. And if I try to learn with a personal project sometimes I have a bad time with code I can't understand. What I mean is that I know language A, but I want to learn B too, so I know how to program, but not in that language. Thanks!

What I do is I look at either a new project I would like to do or an existing one I would like to refactor heavily. Every time I go over what the feature requirements will be and find a language, framework and libraries that will suit the project.

Sometimes I end up rewriting/refactoring from one language into another. This is great approach to learning a new language. However, consider that languages has different idioms, make sure you try to learn the best approaches in your selected language and refactor for those idioms. For example, it is generally a bad idea to write python like you would write C, etc.

If you do not have a project that would be interesting to refactor, take any other idea you have laying around do write that in your selected new language.

In the end, it is better to learn by doing.

For me, the hardest part is not about learning the syntax of a new language (you can easily have a preview with resources like Learn X in Y minutes and then make analogies with others). The tough part is understanding the philosophy of the language and the kind of problems it's aimed to solve. I generally learn new languages when I try to solve problems i've never been in front of, and usually the docs help me a lot.
