> 4x" is a lot slower, and a lot of things are much worse than this. You have to have deep knowledge of the VM (such as knowing how "hidden classes" work in V8) to be able to get JS close to Java. That's a solid argument for only programming in C and Assembly because they are often 4x faster than anything. > Most language features, really. AKA, your preferences are "language features". > Everything is an object So you don't like Python. Or Ruby. > the "Number" type which is totally retarted Very technical argument there. > the terrible "prototype" system So you prefer classical inheritance. Cool. Doesn't mean prototypal inheritance is a bad thing. None of what you mentioned are missing features, they are personal preferences stemming for your own language preference that differs dramatically from Javascript. I'd start by disassociating your opinionated stances from actual weaknesses in the language, of which there are many, and none of them are what you mentioned.
