Programming languages are living things, and they grow and change as time goes by. In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities. Which basically means that if something is a great idea somewhere - it's likely it's a great idea elsewhere as well.

So, many features that appear in new versions of programming languages are actually features that are "inspired by" other languages - ideas that have been proven to work, and that make the programming experience richer and better.

In this presentation, we'll take a look at some of the new features that are coming in C# 12 and TypeScript 5 (5.2 specifically) - and how they are inspired from each other, and from other programming languages and platforms as well.
