Jul 26, 2021 · The generic parameter this function uses is locked in once the type is resolved. That can be handy when some type needs to set the type of your function. For instance here: const sum: ConcatX<number> = (a, b) => a + b; This says that, externally to this function, you declare that the arguments of this function are numbers.
Nov 30, 2015 · function f<U, V>(fn: Function, a: U & Applicative<V>): U & Applicative<Function> { } I am not entirely sure that the return type in my example is exactly what you want.

Jan 24, 2018 · The variable is of a function type, a generic function (the <T> makes the it the signature of a generic function, more type arguments could be in the list) which takes an argument of type T and returns a value of typeT. And then initializes the variable with the identity function which conforms to the declared signature of myIdentity.
Apr 18, 2020 · The type ConverterFunction<T> does not refer to a generic function, so you can't use it when defining Options.

But the language doesn't support that now.
