Request for Assistance: Obtaining Abstract Syntax Tree (AST) with Goja #568
Description
I'm currently exploring the capabilities of Goja and I'm interested in replicating the functionality provided by the Python library pyjsparser. Specifically, I aim to parse JavaScript code and obtain its abstract syntax tree (AST) using Goja.
import pyjsparser
js_code = """
function exampleFunction() {
var number = 42;
var text = 'Hello, World!';
var obj = { key: 'value' };
var arr = [1, 2, 3];
return [number, text, obj, arr];
}
"""
parsed = pyjsparser.parse(js_code)
print(json.dumps(parsed))
output
