I'm a professional PHP, Python and Javascript developer from the UK. I've worked with Django, Laravel, and React, among others. I also maintain a legacy Zend 1 application.
My feelings on this subject are the opposite of that. I work mainly with PHP and using Psalm to catch type issues and enforce use of types has been incredibly useful - it's caught so many issues and made my code souch easier to understand. And any JavaScript type system will be optional, much like in PHP, so I don't imagine it will cause issues with existing code.
