re: Nice post and good examples, thanks! Although I don't understand why so many examples use let over const. I think it's better to use const wherever...
 

Because let will never throw an error and is seen as the successor of var, while const is more restrictive.
You are right though, as long as you write ES6 always use const unless you see you explicitly need to change the variable reference, like for counters and booleans
