We develop the theory of Callias-type operators twisted with Hilbert C -module bundles and prove an index theorem for such operators. As an application, we derive an obstruction to the existence of complete Riemannian metrics of positive scalar curvature on noncompact spin manifolds in terms of ...
The `is` and `as` operators test the type of an object. The `typeof` keyword returns the type of a variable. Casts try to convert an object to a variable of a different type.
Gets the position of the type parameter in the type parameter list of the generic type or method that declared the parameter, when the Type object represents a type parameter of a generic type or a generic method. GenericTypeArguments Gets an array of the generic type arguments for this typ...

The examples in this article do not make use of the double underscore convention. Syntactically, thetypeofkeyword is followed by parentheses which conta...

The usual arithmetic conversions are the implicit conversions that are automatically applied to operands of different arithmetic types for most operators. The purpose of the usual arithmetic conversions is to find a common real type for all of the operands and the result of the operation. The usual...
Functions in TypeScript are the building blocks of readable, maintainable, and reusable code. A function is a set of statements to perform a specific task. Functions organize the program into logical blocks of code. Once defined, functions may be called to access code. This makes the code ...
TypeScript 5.0 Beta shipped with this functionality, we did not document our work for supportingcase-insensitive import sorting in editor scenarios. This is in part because the UX for customization is still in discussion, but by default, TypeScript should now work better with the rest of your ...
