Most in demand front-end and back-end (language/framework)?

Question

I just had an interview at Brilliant.org, and while I had good problem-solving experience according to them, I apparently did not have enough front-end experience. I'm tired of hearing things like this. I'm going to start something up on my own.However, I do want the skills I'm training for to be as transferable as possible. Since there's a big chance whatever I do won't be successful. which is why I'd want relevant experience. I never ever want to hear the dreaded "you're amazing but don't have enough experience" ever again.So what is the most in demand front-end technologies and back-end technologies?I thought for front-end it's ReactJS (which I do have some experience in), but I might be wrong. And I have no clue what it might be for backend. Is it RoR, or Django, or Node/Express, or ASP.Net, or Spring Boot?Does anyone have some ideas?

React is the frontend winner, Vue is good if you look for work in startups, Angular if you're more into enterprise work.
Backend... matter of taste. And each local / regional market is different. PHP has always been big and it has been making good strides technically (use Symfony or Laravel as a first framework).
Python is also a safe bet, Django and Flask are good framework options. Java Spring Boot and C# are good options if you want to work with larger companies. Node is also a good choice in terms of marketability, but I personally prefer one of the "conventional" back end frameworks.
Rust, Go, Haskell, Svelte, Phoenix / Elixir might be exciting, but in terms of market opportunities, it's still relatively small compared to the above. Maybe for when you have more expertise in 2 or 3 of the above.

If you already have some experience with React, Node is probably the best choice. It's in high demand, and it's always nice to have one language on both backend and frontend.Angular is also very popular and it's often used in combination with Node or .NET

From what I see in my network, the most frequent combinations are:- React or Vue on the front (in that order)- Node, Python, RoR, ASPNET-MVC or Laravel on the back (in that order)
