Depends on ,what you want to pursue.
If you see yourself as a web developer (more of front end) then Html, Css and Js are must
For automation projects (mechatronics) c, python would be helpful.
I’m sure there are more however these are good ones to start with.
If you see yourself as ux/ui designer, basic knowledge of front end coding will be helpful to collaborate well with the developer, however it’s not mandatory.
Ux/ui mostly focus on usablity, making wireframing and make making high fidelity prototypes
PS : there is more to it, like business understand, empathy etc
Hope that information helps
