What is an Abstract Syntax Tree?
An Abstract Syntax Tree, or AST, is a representation of the structure of a programming language. It is a tree-like structure that is composed of nodes, each of which represents a language element like a variable, operator, or keyword. ASTs are often used to represent code written in a specific programming language, such as Python or C++.
- An AST is essentially a simplified version of a parse tree.
- The nodes of an AST are abstracted away from the details of the syntax of the language, making it easier to reason about the structure of the code.
- This abstraction allows for more efficient processing, as the details of the language are removed. Additionally, ASTs are often easier to understand than parse trees, as they are more concise and easier to read.
Abstract Syntax Tree vs Parse Tree
Abstract Syntax Trees (ASTs) and Parse Trees (PTs) are two fundamental concepts in computer science and software engineering. Understanding the differences between them is essential for writing efficient and robust code. This blog post will look at both ASTs and PTs and compare their main features.
