Building an Interpreter from scratch

Demystifying how programming languages work under the hood is a rite of passage for any serious software engineer. Dmitry Soshnikov’s 'Building an Interpreter from scratch' provides a clear, hands-on architectural journey into language semantics. Instead of just learning how to use a language, students construct their own custom execution engine. The course systematically breaks down complex compiler theory, starting from AST-interpreters and progressing to high-performance stack-based Virtual Machines and bytecode execution. This practical curriculum bridges the gap between high-level code and low-level execution mechanics, explaining concepts like JIT compilation, transpilation, and the role of LLVM. Developers will explore how closures, lexical scoping, and call-stacks function at the machine level, alongside implementing object-oriented concepts such as classes and prototype inheritance. Perfect for intermediate programmers, systems architects, and tools developers, this course empowers you to design robust runtime environments and write significantly optimized code. By the end, the underlying machinery of engines like V8 or JVM will no longer feel like a black box.
