Abstract syntax trees

An Abstract Syntax Tree (AST) is a visual or structural way to represent the structure of code or expressions. Think of it as a blueprint where each node represents a part of a program, such as an operation or value, organized hierarchically. Instead of focusing on the exact syntax used in writing code, the AST captures the underlying structure and relationships, making it easier for compilers or interpreters to analyze, optimize, and execute the code efficiently. In essence, it's a structured map reflecting the logic and composition of a program.
