> That's amazing. I was just scratching my head about const when I read the article, "so what's the purpose if I can change the value... but I guess I can't re-assign the variable with a new value .... that's it?"
If the value is a primitive, you can't change it. If the value's a reference you also can't change that, but of course you can modify whatever that points to.
Is that what's bugging people about this?

I believe so. I don't make a big issue out of it... but anything carrying the word const I expect it to be fully read-only with no "buts" in between throughout the whole execution of the program. I guess if they used "readonly" as C# it would make more sense?
I still found the article incredibly informative, sadly as someone still stuck working on legacy apps it falls into "...in some near future I'll take advantage of JavaScript new stuff"
