    Introduction to Abstract Syntax Trees

    javascriptJavaScript

    In this lesson, we’ll learn about the key technology used by JavaScript engines and tools like ESLint and Babel to run, lint, and modify your source code. The JavaScript Abstract Syntax Tree (or AST for short) is a JSON representation of your code that is represented by a tree structure. In this lesson we’ll explore that tree structure to get a feel for how code translates to an AST.
