So currently I have experience in Node.js, but just to expand my stack knowledge and for getting backend developer roles, I thought of learning another backend-related language/framework. I have heard about Django, Golang, and Spring. I am mostly trying for backend API roles, and far as I've heard, Django REST framework can be a pain to work with. I've heard there are issues with Golang for package management (like how recently the Gorilla web toolkit is archived) and as for Spring, it's a vast ecosystem to learn so not sure if it's worth investing in. I would like to know which tool/framework to learn, which can help me get high-paying jobs and has a lot of scopes, and also which is great for making REST APIs. Any other tool that can do the job better than these three is also welcome!
