我正在尝试使用动态名称访问对象的属性。这可能吗？

837const something = { bar: "Foobar!" };
const foo = 'bar';
something.foo; // The idea is to access something.bar, getting "Foobar!"

这是我的解决方案：
function resolve(path, obj) { return path.split('.').reduce(function(prev, curr) { return prev ? prev[curr] : null }, obj || self) }使用示例：
resolve("document.body.style.width") // or resolve("style.width", document.body) // or even use array indexes // (someObject has been defined in the question) resolve("part.0.size", someObject) // returns null when intermediate properties are not defined: resolve('properties.that.do.not.exist', {hello:'world'})
