Introduction
This project is an exploratory data analysis based on the Stack Overflow Developer Suvery 2018 conducted by Stack Overflow. Stack Overflow is a privately held website, the flagship site of the Stack Exchange Network created in 2008 by Jeff Atwood and Joel Spolsky.
Each year, Stack Overflow asked the developer community about everything from their favorite technologies to their job preferences. There are 98,855 responses in this public data release.Those responses are considered “qualified” for analytical purposes based on completion and time spent on the survey and included at least one non-PII question.
