Yeah. I didn’t understand what they meant by the wtf there. Seemed to me someone wondered if the Action would have a localised version of i (making this stay lowercase on a phone was harder than it should be) or if it used the same i. So made a simple test for it.
Not really sure it’s a wtf unless they expected a different result.
I think the explanation they provide is a bit lacking as well. Defining an anonymous function doesn’t “create a reference” to any variables it uses, it captures the scope in which it was defined and retains existing references.
The WTF in the C# example seems to be that people don’t understand anonymous functions and closures?
Some of the examples seem to be more “unintuitive for newbies”, but there are still some good ones in there
Yeah, just check the PHP section!
My favourite is
var_dump(true == 'bob') . PHP_EOL; // bool(true) var_dump('bob' == 0) . PHP_EOL; // bool(true) var_dump(true == 0) . PHP_EOL; // bool(false)Yeah. I didn’t understand what they meant by the wtf there.
