The page is a list of examples of Coffescript done in Javascript. Whether they show evidence of Javascript taking features from Coffescript isn't really a subjective question; they do or they don't. I explicitly enumerated which do and which don't.
In terms of "experiencing the times differently", that is subjective, so I guess we did. One blog post from Eich on why he doesn't want to remove braces isn't really holistic, but you might be right in general.
Arrow functions, splats, default params, string interpolation, lexical scopes, classes, destructuring assignments, chained comparisons, for loops.
I'm not sure how you figure you enumerated which do and which don't. Apparently I'm preaching something unpopular, all my comments have been downvoted a bunch.
Here's a nice article showing that CoffeeScript was on Brendan's mind when he was working on Harmony (ES6): https://brendaneich.com/2010/11/paren-free/
He calls Ruby/Python/CoffeeScript "unsyntax" and he doesn't like it I think :P
edit: apparently he does like it, he just doesn't think it would work on the web, he elaborates here: http://intertwingly.net/blog/2010/11/25/Hobgoblin-of-Little-...
