What exactly is it that you want to know?
Are you trying to choose between the two?
If so then try posting a more specific "which one should I choose?" question detailing specifics about your project or situation, or if you are just learning for the sake of it be specific about what you already know and what you want to learn.
Bear in mind that your question is still fairly likely to be closed, but might fare a little better if it is more specific.
Are you trying to understand the syntax / technical differences between the language?
If so then again be specific about what it is you want to know:
- Which is faster?
- Why does X not have Y?
- Are there available benchmarks of the performance between x and y?
- In X I can do Z using, Y how do I do this in W?
Ultimately the trick to asking this sort of question is weighting it so that it can't just degenerate into an X vs Y argument. Being specific about exactly what it is that you need to know is the only way to avoid the inevitable pointless subjective argument bound to follow. (don't think links to X vs Y arguments don't count!)
Remember: If a question can turn into a subjective argument then it will - If it's going to turn into an argument then it's going to get closed.
