Javascript array object return empty array [closed]-CodePudding

I try to filter jsonplaceholder comments to get by id but return empty array

axios.get('https://jsonplaceholder.typicode.com/comments').then((result) => {

 // const arr = _.find(result.data, { postID: 1});
 // console.log(arr);
 console.log(result.data.filter(x => x.postID === 1))

}).catch((err) => {
 console.log(err);
});

CodePudding user response：

Change postID by postId:

console.log(result.data.filter(x => x.postId === 1))

CodePudding user response：

You're comparing postID instead of postId.

Working example at Codesandbox

axios
  .get("https://jsonplaceholder.typicode.com/comments")
  .then((result) => {
    // const arr = _.find(result.data, { postID: 1});
    // console.log(arr);
    console.log(result.data.filter((x) => x.postId === 1));
  })
  .catch((err) => {
    console.log(err);
  });

CodePudding user response：

Log both the result data and the post id property type. So it could either be an absence of data from the response in the request or it could be a flawed comparison because of the "===" operandi
