## About

AST explorer is a web-based utility designed for developers to visualize and analyze the abstract syntax trees (ASTs) generated from source code. It supports multiple language parsers, allowing users to inspect node types, properties, and locations in real time. Hovering over tree nodes highlights the corresponding source code locations, facilitating parser development, compiler design, and AST transformation logic writing.
