Wrong. What makes it powerful is its ubiquity and the fact that it's de facto the only game in town for browser behavior scripting.

Want a constant? Make a global variable and don't change it.

That involved mental overhead (and team co-ordination) that makes it far less simple than "const foo".

Scope in JS is very simple to understand

Simple != intuitive or less prone to bugs. Brainfuck is also simple to understand, just a handful of rules. I wouldn't want to program in it, though...

One of the strengths of js is that every thing is an object(almost). So the bit about "no more need to abuse objects as dictionaries" is a bit odd. Since most things are objects, you get the power to treat functions, types, literals, etc in interesting ways.

Yeah, the only thing you DON'T get is an actual dictionary. Without hidden values coming from prototype, without reserved words, etc.

This proposals retains all that power PLUS gives you an actual bloody dictionary, one of the three more basic data structures in all of programming, without the toil and the million edge cases objects as dicts have.

For me, I almost never use == so it should be gotten rid of.

So what you consider as strengths are the shortcomings, and what you consider as a problem is an actual case that it can be considered a neat feature. The way js is designed, "==" makes more sense, because it lets you use more dynamic equality checking.
