March Highlights

React cruised to its tenth win in a row in March, continuing to show its dominance in the tech hiring marketplace. Python maintained its normal spot at #2 as well. React and Python both maintained more than a 20% share of postings, opening up a large gap between these 2 and the rest of the field. Also interesting is to see the movement after those two, as JavaScript fell back significantly from third to fourth and nearly further.
