I thought the idea of TS is that it strongly types everything so that the JS interpreter doesn't waste all of its time trying to figure out the best way to store a variable in RAM.
The code is ultimately ran in a JS interpreter. AFAIK TS transpiles into JS, there's no TS specific interpreter. But such a huge difference is unexpected to me.
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.
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 😄
