Also, while JavaScript has been a hacky language, ES2015 and ES2016 have really upped the game:
* Classes
* Modules
* Block-scoped variables
* Multi-line strings
* Default parameters
* Template Literals
* Arrow functions
* Promises
* Async/await
And JavaScript keeps eating the world:
"In three months from today, 98% of all Walmart.com traffic will be serviced via Node APIs and displayed with React.js according to Alex Grigoryan, Director of Software Engineering at WalMart Labs. Three months after that, SamsClub.com, Walmart’s second biggest property, will be 100% javascript based. Even their iOS and Android experiences will eventually be done in React Native, a javascript technology that’s made to replace native Java/Objective C coding."

You mean eating the visible world. There's all the code which isn't public facing that runs everything else. For that matter, JS is dependent on layers of code not written in JS, some of which is visible.
Also, it's not like other programming languages don't have the features you listed. JS is playing catchup.
