如何使用数组解构提取嵌套的 object 属性？

Question

I get undefined using this code:

 const json = {"records":[{"recordid":"1694119","recordindex":1,"status":"updated successfully"}],"message":{"returncode":1}}; const { records: {status} } = json; console.log(status);

How to get the expected: "updated successfully"?

Answer 1

Since records is an array, you need to add brackets:

 const json = {"records":[{"recordid":"1694119","recordindex":1,"status":"updated successfully"}],"message":{"returncode":1}}; const { records: [{status}] } = json; console.log(status);
