2021 SO Developer Survey results

Overview:
This year, for example, we observed a significant evolution in the way developers educate themselves. For the rising cohort of coders under the age of 18, online resources like videos and blogs are more popular than books and school combined, a statistic that doesn’t hold for any of our other age cohorts. Overall, the profession is full of new joiners, with more than 50% indicating they have been coding for less than a decade, and more than 35% having less than five years in the trade.
