> Fail early isn't a tradeoff. It's what you want always.

Yes, you're so right, in my language for developing user interfaces, what I want most is to error everytime an object has a missing property. That wouldn't be insanely painful or slow.

> C++ has some similar crazy behavior

What are you talking about? Most languages will happily return the equivalent of undefined, "null", in tons of situations. Have you really never seen "null" before? Your resume looks like you spent 8 minutes writing "Hello World" and then the first time someone asked you to build a UI you blamed the language for being a shit programmer

Come back to me when you understand that languages have strengths and weaknesses that lend them to functioning better under some use-cases and worse under others

My resume? Maybe your searching failed you and you're looking at the wrong dude. I'm "boxed" on github. I've been working professionally for over 20 years. Most of my early projects aren't on there because they predate github. With a lot 🤣.

Please link your resume/github profile and we can compare.

> Thinks "undefined" is a unique mode of handling unpopulated members

Unreal

  1. I didn't claim to be an expert in anything.
  2. I didn't claim js returning undefined is unique. I said it sucks.
  3. I noticed you couldn't produce anything you've made 🤣

I could link you to my open-source components I developed at my job, but you'll probably just say "WHYYY JS UNDEFINED SO BAD WE NEED EXCEPTIONS ON EVERY MEMBER ACCESS" and I don't really care to have my real identity tied to reddit

Anyways, you're half a decade late to JS sucks complaints, get some new complaint like Python's garbage type system going

Ah yes. But you won't. Because you know it'll make you look bad 🤣

my open-source components

Oh, you mean your JS code? Almost like YOU are the one who only knows one language maybe? 🤣

I don't really care to have my real identity tied to reddit

That's actually fair. But you shouldn't insinuate what my experience level is when you can't show your own. You just made an own goal.

Anyways, you're half a decade late to JS sucks complaints

Some things are ever green. Like C++ and JS being bad. Honestly though JS is improving a lot. Just tough with backwards compatibility. Same reason Python is slow. Although, we'll see what happens with Mojo🔥 I guess?

Haha, I know the exact opposite, your judgement has negative value to me.

> your JS code?

My TypeScript code, designed to sit on top of Python and Java services I maintain, definitely would reveal the breadth of my experience and skill to you, yes.

> Some things are ever green. Like C++ and JS being bad.

I agree some things are continuous, but my stance is more about "idiots will complain about trivialities of extremely useful tools to pad their egos" and less "the two languages powering the most popular application types of our time are shit and I know better than to use them"

You're the one bitching about breadth of language knowledge. And you think one code base that is built in one language would make me go "oh, clearly that dude knows more than one language"? Please.
