如何从javascript文件中提取javascript函数

const fs = require('fs');
const fileContent = fs.readFileSync('path/to/your/javascript/file.js', 'utf8');

const acorn = require('acorn');
const ast = acorn.parse(fileContent, { ecmaVersion: 2020 });

function traverse(node, func) {
  if (node.type === 'FunctionDeclaration' || node.type === 'FunctionExpression') {
    func(node);
  }

  for (const childNode of node.children) {
    traverse(childNode, func);
  }
}

traverse(ast, (node) => {
  console.log(node);
});

function extractFunctionInfo(node) {
  const name = node.id ? node.id.name : '(anonymous)';
  const params = node.params.map((param) => param.name);
  return { name, params };
}

const functions = [];

traverse(ast, (node) => {
  functions.push(extractFunctionInfo(node));
});

console.log(functions);
