Turf JS无法正确创建对象

Question

我正在使用辅助函数turf.point()

const feature = turfHelpers.point(coords, properties, { id: properties.id });

properties看起来像这样

properties = {
  id: 1,
  thisWorks: 'no problem'
  foo: {
    thisDoesntWork: 'this is a problem'
    }
  }

当我用turfHelpers.point()创建feature时，它会弄乱对象。嵌套对象不再是object，而是字符串化...

所以，features.properties是

{
  id: 1,
  thisWorks: 'no problem'
  foo: "{
    thisDoesntWork: 'this is a problem'
  }"
}

现在，我无法访问。 feature.properties.foo.thisDoesntWork了，因为它是一根绳子... turf.js为什么要这样做？

让我们以可运行的形式提出问题。

const turfHelpers = turf.helpers;
const coords = [100, 14];
const properties = {
  id: 1,
  thisWorks: 'no problem',
  foo: {
    thisDoesntWork: 'this is a problem'
  }
};
var feature1 = turfHelpers.point(coords, properties, {
  id: properties.id
});
// Print out on console
console.log(feature1.properties); //look OK
console.log(feature1.properties.foo); //also OK
console.log(feature1.properties.foo.thisDoesntWork); //also OK

然后，希望它有助于导致解决方案的讨论。
