Excellent article Tom, thank you. But I need to disagree with the research I did about “70% of companies are looking for JavaScript developers”. I believe the new language to go for is Python with the hype of data science, web development with Django and easiness of coding for everyone. I came across the StackOverflow data and in 2018 was more discussed in the forum than any other, probably even more today. See my article if interested and also the stack overflow source here https://hackernoon.com/data-engineering-the-future-of-data-warehousing-81bc953a9b00#bc34
