Javascript has had a Boolean type at least since ES5; I'm not sure what exactly you're trying to convey there. The lack of a Number type is pretty frustrating for many types of computation, but at least some of them are covered by typed arrays. I'm not sure what you mean by "no decent debugger" either, there's debug tools in every browser plus quite a few for node. "Accessing" a non-existent variable has been a ReferenceError since ES5(http://es5.github.io/#x8.7.1 http://es5.github.io/#x8.7.1). Assigning to a non-existent variable has been a ReferenceError since ES5 as well, in strict mode. What makes you dislike JavaScript so much you'd go on such a rant about it?
