Be it that you are a beginner or an experienced professional, if you are into software engineering, it is very likely that you will need to keep updating yourself with new technologies. Coding and Scripting languages are the bread and butter of most IT engineers. Newer and better languages come up every now and then and it is imperative that you also need to update yourself with some of them based on your job requirements, aspirations and interests. Coding is fun and learning coding in a new language is even more fun. It gives us the kick of creation every time we solve a coding problem. You can even register in Corporate Bootcamp programmes to upskill and reskill yourself in coding.
