I worked on projects using C++, C#, PHP, Python and JavaScript, also Typescript. I learned programming with C. So I am at least at a professional or competent level at each of them.

The language I am most productive in is JS. There is barely any boilerplate, it is easily writeable and supports multiple paradigms. Personally I prefer Typescript and I make it a requirement for projects I lead. I use it for everything unless it is a native application in which case I use C++. Just the language features of JS, compatibility, tooling, platforms where you can run it and so on makes it easily the most useful language on the list. I don’t even consider Python, C# or Java over JS. None of them are any faster or better designed languages, except for C# and that’s mostly improved by TS.

pacman -Syu

Using -Syyu can cause a partial system upgrade if mirrors are out of sync. It leads to higher traffic for mirror owners and it is considered bad practice overall. There are just a few rare cases where it is useful at all.

Forcing anything should always be a conscious decision and never the default.
