Why is svgson an async function?

[davedx]

Looking at the code, it seems that everything is synchronous, so I'm wondering why the export returns a promise?

Yes, I tested it. The whole process is synchronous. Maybe it's better to use parseSync .
index.js

const { parse, stringify } = require('svgson')
console.log('before')
parse(`
  <svg>
    <line
      stroke= "#bada55"
      stroke-width= "2"
      stroke-linecap= "round"
      x1= "70"
      y1= "80"
      x2= "250"
      y2= "150">
    </line>
  </svg>`).then((json) => {
  console.log(JSON.stringify(json, null, 2))
})
console.log('after');

svgson.cjs.js

function svgson() {
  // console.log('parse', 'cjs')
  for (var _len = arguments.length, args = new Array(_len), _key = 0; _key < _len; _key++) {
    args[_key] = arguments[_key];
  }

  return new Promise(function (resolve, reject) {
    try {
      var res = svgsonSync.apply(void 0, args);
      console.log('resolve 前');
      resolve(res);
      console.log('resolve 后');
    } catch (e) {
      reject(e);
    }
  });
}

result:

before
resolve 前
resolve 后
after
{
  "name": "svg",
  "type": "element",
  "value": "",
  "attributes": {},
  "children": [
    {
      "name": "line",
      "type": "element",
      "value": "",
      "attributes": {
        "stroke": "#bada55",
        "stroke-width": "2",
        "stroke-linecap": "round",
        "x1": "70",
        "y1": "80",
        "x2": "250",
        "y2": "150"
      },
      "children": []
    }
  ]
}

While have no impact on the main package, I am leaving both versions. However I want to hear some more examples, use cases allowing us to choose if remove the async layer, leaving everything sync and publishing it as a new major version.
