type C = number | booleanTry Partial<Type> Released: 2.1 Constructs a type with all properties of Type set to optional. This utility will return a type that represents all subsets of a given type. Example inte
In the first example, we added types for the parameters x and y and the return type of the function. TypeScript can infer the return type using the types of the parameters. This means that optionally we can leave the return type out....
On compiling, it will generate the following JavaScript code. letbool=true;// let bool1: Flatten<boolean> = "s"; // Error as string can't be assigned to booleanconsole.log(bool); Output true This way, you can use the conditional types in TypeScript. You can use the generic types, ...
A bulk type describes a homogeneous collection of values. These values are described by another type which is given as a parameter to the bulk type constructor. Many bulk types such as sets, lists and relations are already familiar and widely used in data-intensive applications. Additional bulk...

void— type with an empty set of values. It is anincomplete typethat cannot be completed (consequently, objects of typevoidare disallowed). There are noarraysofvoid, norreferencestovoid. However,pointers tovoidandfunctionsreturning typevoid(proceduresin other languages) are permitted. ...
container::iteratorThe type of iterators. Provided by vectors, deques, lists, sets, multisets, maps, multimaps, and strings. container::const_iteratorThe type of constant iterators. Provided by vectors, deques, lists, sets, multisets, maps, multimaps, and strings. container::reverse_iterator...
You first use the GetEnumerator method to get your hands on an object that implements the IEnumerator object. This separation between the IEnumerable and IEnumerator interfaces allows you to have multiple iterators on the same collection. Since IEnumerable is such a popular interface, .NET languages...
