Need some advice

Today I came out some question

I am really interested in blockchain development but mostly I saw is from solidity or JS but my skills are good at python do I need to learn JS?

you will need to know at least some JS, depending on what you want to do you could do it in Python too, but most of the web development part is done in JS. Solidity is closer to JS too.

you also have videos specific to how to work with python (only some examples, there are more):

i see noted friend i gues i need to learn JS this holiday season thank you
