Course Description

How do programming languages work under the hood? What’s the difference between a compiler and interpreter? What is a virtual machine and JIT compiler? And what about the difference between functional and imperative programming?

There are so many questions when it comes to implementing a programming language!

In this course, we will learn about compilers AST interpreters and virtual machines. We will further explore basic expressions and variables in interpreters and learn about variables and environments. We will also explore built-in and native functions, user-defined functions, and call stack and recursive calls. Lastly, we will learn about OOP, class inheritance, and code isolation.

By the end of the course, we will implement a full AST interpreter for our programming language.
