This is a question I get asked frequently by people just starting out or thinking about moving into the development world. This question is not easy to answer, there are several variables that can change the answer, I know this is not what you would like to be reading. Personal questions, both from the questioner and the answerer, can change the answer. I will assume that the majority of readers are people entering or moving into the technology market, specifically development. With this in mind, we know that the learning curve is probably one of the most important factors, followed by pay and the number of available seats. In the listing below, I will explain why I chose the languages and what personally makes me believe they are the ideas for you to start learning.
Flowchart: Which language to learn first
During my search for other sources and opinions, I came across a very interesting flowchart that helps to decide which language to choose. It has starting points and questions based exactly on personal issues, which may interfere with your decision. Unfortunately it is in English, I will try to translate to Portuguese soon.
