Its really not, have you noticed how an enum is transpiled? you end up with a function... a lot of other things follow the same pattern.
No they don't. Enums are actually unique in being the only Typescript feature that requires code gen, and they consider that to have been a mistake.
In any case that's not the cause of the difference here.
This isn't true, there are other features that "emit code", that includes: namespaces, decorators and some cases even async / await (when targeting ES5 or ES6).
Ah yeah I forgot about namespaces. I don't think they're a popular feature.
The other two only generate code for backwards compatibility. When targeting the latest JavaScript versions they don't generate anything.
Ok decorators are technically still only a proposal so they're slightly jumping the gun there, but the point remains.
Nope, have not noticed because I hate JavaScript with a passion. Thanks for educating me.
Just FYI the example that person gave would absolutely not explain a huge performance difference. I don't think they understand what they're looking at.
fair enough :D but it does happen and there are reasons for that: https://stackoverflow.com/questions/47363996/why-does-an-enum-transpile-into-a-function
Thanks! I hate JavaScript even more now ๐
