AST Code Generator

Build a tool that parses JavaScript code into an Abstract Syntax Tree (AST) and then converts the AST back into formatted JavaScript source code.

Capabilities

Parse and Generate Code

• Parsing the code const x = 5; and printing the resulting AST produces valid JavaScript code @test
• Parsing the code function add(a, b) { return a + b; } and printing the resulting AST produces valid JavaScript code @test
• Parsing the code with JSX const elem = <div>Hello</div>; and printing the resulting AST produces valid JSX code @test

Synchronous Operations

• Using synchronous parsing and printing methods for the code let name = "Alice"; produces the expected output synchronously @test
