I am java backend developer with 1.5 years of experience.i am looking for a niche line which will get me big packages in near future. Should I go for learning front end technologies such as react/angular or should I focus on dsa concepts?
Niche and frontend should not be in same sentence. Focus dsa for now, then system design. Language can be anything ur work demands but if u really want niche u can think of maybe elixir
