Why is modern JS (TS especially) not a "real programming language". I have never once been bitten by == vs === or the crazy automatic type conversions people use to demonstrate that JS is not a "real" programming language. I especially don't understand why people would want to write a front-end in Go. React already provides a great front-end experience. If you're doing something that requires high-performance, then use c++ compiled to wasm or something similar. But why Go? It's not as performant as C++ and I don't think it provides a UI development experience as good as React.
