opCode

In this book, we jump into a virtual machine, compiler and opcodes, without needing to read about parsing first. The language is already written, meaning you can get up and running and dive into the source code of a working language right from the start. Discover how I went about adding some very useful features to a language, such as multi-variable assignment, decoupling assignment, string interpolation, short-circuiting operators, for loops, scoped if expressions, and more. We review how opcodes make these things work in the virtual machine.
