A recent survey by Sacha Greif gives a comprehensive overview of the current state of the JavaScript world.
Front-end, full-stack, testing, mobile: If you’re working with JavaScript in any way this survey has you covered! It gives you a great overview of what’s in use right now and what might be in the near future.
The survey will be done annually. So, it should be possible to see where the JavaScript world is headed and which predictions turned out to be true by next year.
If you want to participate in next year’s edition you can subscribe to the survey mailing list on the website.
