import ecmagen from '@tabaneproject/ecmagen';
import acorn from 'acorn';
import fs from 'node:fs';

// Use ECMAGen
let text = fs.readFileSync( __dirname + '/testcode.js', { encoding: 'utf-8' } );
let ast = acorn.parse( text, { ecmaVersion: 2020 } );
let output = ecmagen.generate( ast );

// Write Output
fs.writeFileSync( __dirname + '/testcode.copy.js', output );

Hello World Program

// Import ECMAGen
import ecmagen from '@tabaneproject/ecmagen';

// Use ECMAGen
let ast = {
    type: 'BinaryExpression',
    operator: '-',
    left: { type: 'Literal', value: 100 },
    right: { type: 'Literal', value: 60 }
};
let output = ecmagen.generate( ast );
console.log( output ); // 100 - 60
