Why does C# compiler create private DisplayClass when using LINQ method Any() and how can I avoid it?
To understand the “display class” you have to understand closures. The lambda you pass here is a closure, a special type of method that magically drags in state from the scope of the method it’s in and “closes around” it. …except of course that there’s no such thing as magic. All that state has to … Read more
when use JS .includes() vs .some()? [closed]
some takes in a callback function where you can write your own logic to determine if an array contains some element which matches the conditions you wrote. includes does a generic equalTo comparison on every element and will return true if at least one element in the array is equal to the value to find.
Difference between any/interface{} as constraint vs. type of argument?
Beside any and interface{} being type aliases — hence, equivalent in usage —, there is a practical difference between any as type parameter and any as regular function argument, as in your example. The difference is that in printAny[T any](foo T) the type of foo is not any/interface{}, but it’s T. And T after instantiation … Read more
PostgreSQL – IN vs ANY
No, in these variants are same: You can see – the execution plans are same too: postgres=# explain select * from foo1 where id in (select id from foo2); ┌──────────────────────────────────────────────────────────────────┐ │ QUERY PLAN │ ╞══════════════════════════════════════════════════════════════════╡ │ Hash Semi Join (cost=3.25..21.99 rows=100 width=4) │ │ Hash Cond: (foo1.id = foo2.id) │ │ -> Seq Scan on … Read more

scala – Any vs underscore in generics
OK, I figured I should have my take on it, instead of just posting comments. Sorry, this is going to be long, if you want the TL;DR skip to the end. As Randall Schulz said, here _ is a shorthand for an existential type. Namely, class Foo[T <: List[_]] is a shorthand for class Foo[T … Read more
JavaScript/jQuery equivalent of LINQ Any()
These days you could actually use Array.prototype.some (specced in ES5) to get the same effect: array.some(function(item) { return notValid(item); });
any() function in Python with a callback
How about: >>> any(isinstance(e, int) and e > 0 for e in [1,2,’joe’]) True It also works with all() of course: >>> all(isinstance(e, int) and e > 0 for e in [1,2,’joe’]) False
Good way to get *any* value from a Java Set?
A Set<T> is an Iterable<T>, so iterating to the first element works: Set<T> things = …; return things.iterator().next(); Guava has a method to do this, though the above snippet is likely better.
