Can you clarify what you're talking about here with regards to React? I can see calling JSX a DSL, but React is a language now? And there's no JS / TypeScript in your React code base?
In a way, it is. Whenever you write some module in your project, you're effectively designing a language. Every function you add is a new verb, every type you define is a new noun[0] - and the relationships between them form the grammar. It may sound trivial, but I think it's an important and underappreciated point. Modularizing and abstracting is done by building languages on top of other languages.
We usually make a distinction between what is a "library" or "module" and what is a "language", by... it's hard to capture the distinction exactly, but my guess is that we reserve the term "programming language" for languages that a) define a large, highly composable set of building blocks, and b) have complex translation into a lower-level language, ultimately yielding executable code. Whatever the distinction could be, in reality, it's a spectrum.

[0] - Well, a piece of a noun phrase. Maybe. I'm not a linguist.
I base my opinion on my own interpretation: for me modern React looks a lot like the offspring of QML and a flavour of Lisp.
But I do note that your examples are from quite a narrow sector. TypeScript, Go and React are all languages. TypeScript is a nice facade over JavaScript, and React is ... well, a very powerful DSL.[ß] Go is very much a Google project, developed perhaps more out in the open than in a traditional open-source sense.
As I understand, TensorFlow was originally an internal Google project, which they at some point decided to open up. It may have had something to do with their TPU cloud offering or not. If we wanted to compare low-level language or domain material, we should probably take a look at something like Boost. People who do C++ tell me that Boost is a pretty good approximation of C++ standards' evolutionary playground. And if we're going for new languages, shouldn't we also include Rust? It was backed and promoted by Mozilla, but how much of its development was driven solely by Mozilla, and how much was done by the interested community at large?
