How to start using acorn-loose CDN


const acorn = require('acorn-loose/dist/acorn-loose-cjs.js'); // Use the CommonJS version
const traverse = require('babel-traverse');

async function parseAndTransform(code) {
  try {
    const ast = await new Promise((resolve, reject) => {
      acorn.parse(code, { ecmaVersion: 6 }, function(err, ast) {
        if (err) return reject(err);
        resolve(ast);
      });
    });

    traverse(ast, {
      // Add your custom transformations here
    });

    const transformedCode = babel.t.print(ast).code;
    console.log(transformedCode);
  } catch (error) {
    console.error('Error parsing code:', error.message);
  }
}

parseAndTransform(`const x = 1;`);
