I am shocked to not see a reference to Taylor Swift’s hit song Blank Space anywhere in the article!

#12I wish enum was never part of TypeScript. It’s this one odd thing unlike the rest.
Am I forgetting any or is it the only feature that actually generates code rather than just being extra annotation?

#13I'm a little confused about when I'd use this, if I'm quickly iterating on code as I develop it, probably I also want to know whether it type checks, right?

Agreed. It looks OK on the surface, but if you need enums then TS enums is going to end up in frustration.

Am I out of date? Does someone know something I don't?

Lots of TypeScript features generate code: namespace, async/await, yield, decorators, object spread, varargs, etc.*
`const enums` (beyond enums) are especially odd. They rely on type information to emit code.
* Subsequent to their release in TypeScript, EcmaScript versions now support some of these.

TS language server will do that for you as go along

What's not explained by the quoted excerpt?
Instead of writing, e.g. `const n = someValueThatYouKnowIsANumber;`, you should write `const n = someValueThatYouKnowIsANumber as number;`
(well, really, you shouldn't write either, casts are bad. But, yknow.)

So, since they're now a part of JS - aside from namespaces and enums (which are discouraged) - none of those features generate code anymore.
Moreover, aside from namespaces and enums (which are discouraged), none of those features were incorporated into TypeScript until they were on track for inclusion into JS. They weren't taken from TypeScript and imported into JS; TypeScript took them from the ECMAScript people.
Being able to compile TypeScript by just stripping types has become a design principle of the language. For better or for worse, the TypeScript team steadfastly refuses to try to innovate on runtime language features at this point.

Namespaces do as well, but I think it's just those two.
