High load and multithreading in node js?

Question

JavaScript

Hello, I'm writing a fullstack project for a portfolio, something like a social network, I'm thinking of writing entirely in JS, since I'm currently studying JS. So far, there have been no problems with the front. Interested in the question from the title.

• How to organize a highly loaded server on a node?
  
• Or is it best to use ruby ​​or go for such purposes?
  
• Why am I asking, since I don’t know any ruby ​​at the moment, and now the question arose to continue writing completely in JS using node or take something else for the backend?
  

Answer 1

How to organize a highly loaded server on a node?

Load it)
But seriously, the load is not about programming languages, but about scaling and architecture. You are too early.
And if you still want to break your head, then start with the fact that there should be more than one server. The rest of the awareness will start to appear later

Answer 2

Go to dev ops.
Or use Amazon/Google services etc.

Answer 3

So far, you have not yet fully formed the concept of what heavy loads are and how to manage it all.
