How to make your own programming language in JavaScript
What's cool about Esprima syntax is that there are tools that generate code based on their AST. An example is escodegen which takes Esprima AST as input and outputs JavaScript code. You can think that you can use just strings to generate code, but this solution will not scale. In this tutorial, I show only a single if statement but you will run into a lot of problems if you will have more complex code.
