Things you hate/don't like about JS/Javascript/ECMAscript/ES. Or what do you think are the issues

@Artemix yep

@Artemix If with support, what you mean is, JS implementation by various browsers, that have their own version. Some times, they follow standards and sometimes does some changes. Like the new date constructor. Chrome supports some format to create new date with constructor while safari does not.?
They yeah. This is pain in the ass

@Artemix do you implement data structures and algo. in JS ?

@jAsE JS is slow ... then what about python?
