Implicit indexer access in object initializers Enable ref locals and unsafe contexts in iterators and async methods Enable ref struct types to implement interfaces Allow ref struct types as arguments for type parameters in generics. Partial properties and indexers are now allowed in partial types. Ove...
C# has these great constructs built-in: Generics, partial classes, anonymous types, iterators, nullable types, static classes, delegate interface. Implicit types, object and collection initializers, auto-implemented properties, extension methods, query and lambda expressions, expression trees, partial meth...
Consult Python’s itertools for examples of tool functions for iterators. For JavaScript, each tool function for iterables should come in two versions: one for synchronous iterables and one for asynchronous iterables.Immutable data It would be nice to have more support for non-destructively ...
Async iterators, adding syntactic support for asynchronous iteration using the AsyncIterable and AsyncIterator protocols. The feature makes it possible a for-wait-of iteration statement while adding syntax for creating async generator functions and methods. Adding the s (dotAll) flag for regular express...
following, I came through while re-reading stroustrup is writing a program using iterators (Chapter3;Iterators and I/O). This is nothing new and just a iteratorized manifestation of example II above.. but yes, different clothing! ostream_iterator<string> oo(cout); ...
As permitted but not required by the C++11 Standard, SCARY iterators have been implemented. Other C++11 Enhancements Range-based for loops. You can write more robust loops that work with arrays, STL containers, and Windows Runtime collections in the form for ( for-range-declaration : expression...
create an iterator object and use it in "for" statement: C Java JavaScript use the same iterable in "for" statement again: Why? The root cause is in the __iter__() method. When it called, we should return an iterator with the internal position pointer reset to 0. Here is the corre...

Closed over variables won't be freed up by JavaScript's garbage collector. When you use variables inside closures, the memory isn't freed up by the garbage collector because the browser feels that the variables are still in use. Hence, these variables consume memory and bring down the perform...
When a and b are set to "wtf!" in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly ...
