I haven’t dealt with a larger JS/Node Project in a while, but I like this approach to using TS features in JS.
so he does all of this because he dislikes transpiling because supposedly it makes debugging etc harder? does he know about sourcemaps?
he also says he doesnt like type information in his code, so he adda them as comments. the type information is still there, how is this an improvement?
The issue with transpiling is that the code that’s running in production is not necessarily the one that’s been tested. A source map doesn’t fix that.
I loathe this line of reasoning. It’s like saying “unless you wrote assembly, compiling your code could change what it does.”
Guess what, the CPU reorders/ellides assembly, too! You can’t trust anything!
I do this daily and believe me when I say that I’d trade my kidney for the ability to use TS natively. This looks good on paper but jsdoc notation has lots of flaws and you literally can’t do some things with it. Also, it doesn’t check if the function actually does the thing you described so it needs manual review every time it’s changed.
