Generic typeFor C # Programmers, Typescript generics are familiar, basically consistent design.Type constraintsC # uses the WHERE keyword to mark type constraints, and typescript uses the extends keyword within angle brackets for the same effect.In the following example, Iexample constrains the generics to be imyinterface and his derived class.If used like this, it can be constrained to inherit both Classon
