there could be at least one difference - case when you need to pass variable to some other function, for example:

You can turn Duration(int t_seconds) into a template function that can accept an int and set it to deprecated.

You can find an authoritative answer in microsoft/TypeScript#16 (wow, an old one); it is specifically explained in this comment:

That's because of document.all [...], a quirk that gets special treatment in the language for backwards compatibility.

But what could be the purpose of operator auto() = delete?

What would be the purpose of the following function?

There could be many causes for this problem, try to: install js extentions If doesn't work try to delete the .vscode folder under your home dir and reinstall vscode, this should solve the problem.

The conditional operator only evaluates what's necessary, but you have a precedence problem.

First of all, the conditional operator is indeed guaranteed to use short-circuit evaluation, meaning it only evaluates what's necessary.

From the paper on std::byte (P0298R3): (emphasis mine)

Design Decisions

std::byte is not an integer and not a character

The key motivation here is to make byte a distinct type – to improve program safety by leveraging the type system. This leads to the design that std::byte is not an integer type, nor a character type. It is a distinct type for accessing the bits that ultimately make up object storage.

As such, it is not required to be implicitly convertible/interpreted to be either a char or any integral type whatsoever and hence cannot be printed using std::cout unless explicitly cast to the required type.

Furthermore, this question might help.

From this blog post by Eric Niebler, whose range-V3 library heavily influenced C++20 ranges

... custom view types can inher[i]t from view_interface to get a host of useful member functions, like .front(), .back(), .empty(), .size(), .operator[], and even an explicit conversion to bool so that view types can be used in if statements

Clang and GCC are correct to reject it. It's pretty straightforward:

[expr.cond]

2 If either the second or the third operand has type void, one of the following shall hold:

• The second or the third operand (but not both) is a (possibly parenthesized) throw-expression ([expr.throw]); the result is of the type and value category of the other. The conditional-expression is a bit-field if that operand is a bit-field.
• Both the second and the third operands have type void; the result is of type void and is a prvalue.

The wording is pretty precise here. It says one operand is a throw-expression when the first bullet applies. And (std::cout << "smth\n", throw 0) is not a throw-expression. It's parenthesized comma expression.

So we can only be in the case of the second bullet, but its conditions don't hold either. So a "shall" requirement is broken, and the program is thus ill-formed.

Now, MSVC may be offering an extension around this, but it's not standard.
