Templates in C++ vs Generics in Java

Templates and generics allow us to achieve very similar results using very similar code syntax in C++ and Java respectively. But despite that, the implementation of these two features and their semantics are vastly different under the hood.

Syntax and Usage

Templates

Let us consider first the case of a template called Pair in C++.

While Typescript can make working with frontend frameworks like Angular and Vue a whole new revelation, using it on backend projects can have equally pleasing results.
