The results of this year Stack Overflow survey have been published: https://survey.stackoverflow.co/2023/ There is a lot to go through, so if you prefer it in a video format, these kinds of videos can help and also provide some comments on the raw data that you see.
Mostly the great feedback from IDE’s and official product documentation like MDN and the IBM documentation.
I have started to use Copilot and Copilot Chat, but it mostly seems to help with doing easy things much faster, it hasn’t really helped helped with actual problems. Bing chat is sometimes a lot faster though compared to searching the slow IBM documentation website.
