... what? Typescript isn't Javascript, just like C++ isn't C. They're two completely separate languages controlled by two completely separate entities.
Typescript is cool but it's not a replacement to Javascript. I don't see the point of implying that not using Typescript is "not nice".
They are not two separate languages at all, TS is a superset of JS and exists within the JS ecosystem and is designed so that JS projects can be incrementally migrated to TS, it's one of the first things in the documentation.
