Question

How do computer scientists build programming languages ? Are there any programming languages we need to learn to build a programming language? Comment your knowledge below 👇. So we can increase our knowledge of the ocean .

Answer 1

Akash Pokhrel, that is a deep and interesting question!
To build a new programming language, computer scientists typically use an existing one that gives both low-level control for performance and system access, and high-level expressiveness for prototyping quickly.
In essence, one can use any Turing-complete language (https://en.wikipedia.org/wiki/Turing_completeness ) to implement another one, but the design choices including speed, safety, portability etc. will influence which one you choose.
You will probably need to learn compiler theory, type systems, syntax trees and IR. Also, compiler construction tools like LLVM or ANTLR can be quite useful. Strong skills in C,C++ or Rust and knowledge of assembly and how computers execute instructions are usually required.

Thank you.

Answer 2

for instance: Python was build be inspiring of C and Ruby, and Perl....

but what about the first programming language? and about C and Pascal?
if you don't know programming, you must need a logic to build something....
