禁止类型别名和接口中的空类型参数。
¥Disallow empty type parameters in type aliases and interfaces.
TypeScript 允许在类型别名和接口声明中使用空类型参数列表;但是,通常不鼓励这种做法。允许空类型参数列表可能会导致代码不明确或模棱两可,其中泛型类型的意图不言而喻。此规则不允许在类型别名和接口声明中使用空的类型参数列表。
¥TypeScript permits the use of empty type parameter lists in type alias and interface declarations; however, this practice is generally discouraged. Allowing empty type parameter lists can lead to unclear or ambiguous code, where the intention of the generic type is not self-evident. This rule disallows empty type parameter lists in type alias and interface declarations.
