Hi, I am an Android native Developer with an year of experience in it. I use Java/Kotlin to build apps. Apart from indulging myself into Android Development, I want to learn some other technnology/languages. It would be very kind of you people if you let me know what I should learn that's going to benefit me considering I am Android Developer. I am considering Javascript and node.js to learn as it has benefits over Java micro services to build APIs. I don't want to have only one specialization. I think it's better (professionally) to come across as versatile and able to work on different platforms.
