WebNov 17, 2024 · If you define talk as a generic function you allow any class to participate in code that calls talk (e.g. a library), this is a way to allow extensions without having to close the set of possible values, unlike using something like typecase in a function where you can only list a predefined set of cases. In JavaScript, a generic function is a function that can work with values of different types, rather than a specific type. This is achieved through the use of type parameters or by dynamically checking the type of the value being operated on.

WebIn this section, we’ll explore the type of the functions themselves and how to create generic interfaces. The type of generic functions is just like those of non-generic functions, with the type parameters listed first, similarly to function declarations: function identity < T > ( arg: T ): T {. return arg; } WebIn the definition of a generic function that uses such a type variable T, the type represented by T is assumed to be a subtype of its upper bound, so the function can use methods of the upper bound on values of type T. def largest_in_absolute_value(*xs: T) -> T: return max(xs, key=abs) # Okay, because T is a subtype of SupportsAbs [float].
