Let's make a programming language. Variables

Aug 05 2026
Author:

We continue building our own programming language from scratch. In this video, we'll take the next step by adding variables to the language.

And stay tuned for the next webinar.

So far, our programs have consisted of a single expression built from smaller language constructs. Now it's time to evolve the language. Instead of parsing a single expression, we'll introduce a list of declarations, allowing our language to support variable declarations and laying the groundwork for more complex programs.

During the video, Yuri will walk through the implementation step by step, showing how variables are represented and processed in our language, and how to add this functionality to your language in C++.

This video is designed for developers who want to understand how programming languages work under the hood—not just how to use them.

Have fun watching this video and coding :)
