Yes, it most literally and inarguably is:

• ISO/IEC 21778 - Information technology — The JSON data interchange syntax

8 Numbers A number is a sequence of decimal digits with no superfluous leading zero. It may have a preceding minus sign (U+002D). It may have a fractional part prefixed by a decimal point (U+002E). It may have an exponent, prefixed by e (U+0065) or E (U+0045) and optionally + (U+002B) or – (U+002D). The digits are the code points U+0030 through U+0039.

It will cause casting errors in other languages that have badly written, non-standards compliant, JSON parsers, as 1 and 1.0 being the same is part of the official JSON ISO standard and has been for a long time: https://json-schema.org/understanding-json-schema/reference/numeric

As an abstract system, yeah, that is mechanistically how it works. If you live your life and make real world decisions based on an abstract system that doesn’t accurately and wholistically model the real world, then you’re either lying to yourself, or us, or you don’t understand the purpose of money and capitalism in the first place.

Because that object is of a type where that member may or may not exist. That is literally the exact same behaviour as Java or C#.

If I cast or type check it to make sure it’s of type Bar rather than checking for the member explicitly it still works:

And when I cast it to Foo it throws a compile time error, not a runtime error:

If anyone thought we were heading to a future of lower power consumption they were deluding themselves. We can lower emissions by eliminating fossil fuels, but per capita net power consumption will, on average, continue going up, because it will still always correlate with getting useful physical work done.

Western countries need to figure out that the future will lbe dominated by who can produce the most clean energy, the cheapest.

You do not have a right or obligation to leverage your advantage at the expense of everyone else, no matter how many Ayn Rand loving psychopaths will try and argue otherwise.

None of that nitpicking changes the core point that they’re misconfiguring a dev environment and blaming the language.

To play devil’s advocate to that, why is it better that a language is monolithic vs having its various components be independent let different frameworks mix and match different parts?

Interpreted languages don’t have compilers, and one of the steps that compilers do is LINTING. You’re literally complaining about not configuring your compiler properly and blaming it on the language.

I think that might be user error as I can’t recreate that:

K, well configure your linter the way a professional Typescript environment should have it configured, and it will be there too. Not to be rude but not having a linter configured and running is a pretty basic issue. If you configured your project with Vite or any other framework it would have this configured OOTB.

Pretty much the only language that handles this worse is Python (and maybe Lua? I don’t really know much about Lua though).

This is the case for literally all interpreted languages, and is an inherent part of them being interpreted.

However, while I recognize that can happen, I’ve literally never come across it in my time working on Typescript. I’m not sure what third party libraries you’re relying on but the most popular OAuth libraries, ORMs, frontend component libraries, state management libraries, graphing libraries, etc. are all written in pure Typescript these days.

Oh I’m sorry, I was waiting for you to name a more successful cross platform development language and framework?

Oh, you’re listing Java, and Xamarin, and otherwise rewriting the same app 4 times? Cool beans bro. Great resourcing choices you’ve made.

All filled with thousands of dependencies badly managed through npm to overcome the lack of a standard library actually useful for backend stuff.

Bruh, this is the dumbest fucking complaint. “Open source language relies on open source packages, OMG WHAT?!?!!”

Please do go ahead and show me the OOTB OAuth library that comes with your backend language of choice, or kindly stfu about everything you need being provided by the language and not by third party libraries.

I would somewhat disagree. These days virtually every popular library on npm is pure typescript and every new project I see at a company is pure typescript, with only legacy migrations of old systems still mixing the two.

A) yes, that’s how interpreted languages work.

B) the very simple, long established way to avoid it, is to configure your linter:

I haven’t used Perl though, what do you like better about it?

Honestly the meme of ‘JavaScript bad’ is so tired and outdated it’s ridiculous. It made sense 14 years ago before invention of Typescript and ES5/6+, but these days it basically just shows ignorance or the blind regurgitation of a decade old meme.

Typescript is hands down the most pleasant language to work in, followed closely by the more modern compiled ones like Go, Swift, C#, and miles ahead of widely used legacy ones like Java, and PHP etc. and the white space, untyped, nightmare that is python.

I’m like 99% sure that it’s just because JavaScript / Typescript is so common that for anyone who doesn’t start with it, it’s the second language they learn, and at that point they’re just whiny and butthurt about learning a new language.

Lol name one outside of it’s well known equality rules that linters check for.

Also, name the language you think is better.

Because for those of us who have coded in languages that are actually bad, hearing people complain about triple equals signs for the millionth time seems pretty lame.

Yeah. Try and follow the conversation.

Multiple competitors just results in them all agreeing to raise prices when taxes are lowered.

Price signalling happens in situations with low competition, in a healthy, competitive market, if you raises prices someone will undercut you to take your business.

Out of curiosity, how do you propose increasing the number of competitors? Or is this a situation of “gee, that would be nice. Oh well, I guess nothing can be done.”?

You literally just break up grocery store companies and stop them from merging in the future. The solution is not complicated.

No I didn’t, price control laws don’t work. Companies will find another way of maximizing profits and screwing you.
