With the advent of approaching, an unprecedented response to the JS Developer Survey ended, the investigation has recovered more than 5,000 copies, exactly 5,350 questionnaires, I can't wait to share the results with you. Before sharing, first thank everyone involved in the survey developer.

This is the best time for the JS community, and I'm excited about the next survey. I've never been so interested in doing something high, and next time I'm going to do some improvement. Specifically, I'm going to put the questionnaire on GitHub a few weeks before the start of the survey, so that you can negotiate the "problem" and the "options" to get more accurate results and avoid the "I'm shocked that you didn't include Emacs" in a similar situation.

OK, now we're going to report the results. I will keep the results fairly communicated so that you can draw your conclusions.
