Honest question, not playing. What is exactly exciting about it? 2020 is around the corner and the language created back in 1995 is only now getting features that have been standard in many other languages, either as part of the core language or the standard library for decades.
It's exciting to see the language that we use for the web gain these features (albeit late)! These changes will allow us to follow better programming practices with less overhead.
Well, I'd think that was pretty obvious, right? It's exciting because if you spend the day writing JavaScript I don't give a hoot that another language has had that feature for decades because I don't get to use that other language.
Are you implying that no other languages ever add features that other languages have? All languages except JS are feature complete? Come on..
Well now, having an option to use other languages to script web pages, that would be exciting.
The better JS gets, the more I want to use it. JS with Promises + async/await is now one of my favorite languages.
How do you cancel promises?
I can write things in Javascript 5x faster than I can write things in C#. I am finally convinced .NET Core is inferior to Node for that reason, unless I am writing something that needs to be super accurate/performant.
