I am trying to filter an object from an array of objects. Below is the array of the object.

const groupsList = [
    {
    "groupId": 1234,
    "adminId": 52,
    "name": "HHLC Health co",
    "directorName": "Mr Daric",
    "fax": "5556565655",
    "email": "test@test.com",
    "status": 1,
    "address1": "Akshya Nagar 1st Block 1st Cross",
    "districtName": "Berkshire",
    "addedDate": "2020-02-01T04:44:54.000Z",
    "lastModified": "2020-02-25T10:30:47.000Z"
    },
    {
    "groupId": 12335,
    "adminId": 52,
    "name": "Appolo Health Group",
    "directorName": "Mrs Fatima",
    "fax": "5556565655",
    "email": "test@test.com",
    "status": 1,
    "address1": "Akshya Nagar 1st Block 1st Cross",
    "districtName": "Berkshire",
    "addedDate": "2020-01-13T04:44:54.000Z",
    "lastModified": "2020-03-14T10:30:47.000Z"
  },
  {
    "groupId": 546,
    "adminId": 52,
    "name": "Highlights Health LLC",
    "directorName": "Mr Jordan",
    "fax": "5556565655",
    "email": "test@test.com",
    "status": 1,
    "address1": "Akshya Nagar 1st Block 1st Cross",
    "districtName": "Berkshire",
    "addedDate": "2020-02-13T04:44:54.000Z",
    "lastModified": "2020-02-14T10:30:47.000Z"
  }
]

below is the Object which i want to filter from above array.

const objectReady = {
  "groupId": "1234",
  "name": "Health",
  "addedDate": "01-02-2020",
  "lastModified": "25-02-2020"
}

What I have tried:

Here what i have tried with the lodash plugin.

JavaScript

_.filter(groupsList, obj => moment(obj.lastModified).format('DD-MM-YYYY') === objectReady.lastModified || obj.name.toLowerCase().includes(objectReady.name.toLowerCase()) ||
                Number(obj.groupId) === Number(objectReady.groupId));

above code works fine just for a single condition,
but for multiple values it is not filtering data.

Expected Result should be :

JavaScript

[{
    "groupId": 1234,
    "adminId": 52,
    "name": "HHLC Health co",
    "directorName": "Mr Daric",
    "fax": "5556565655",
    "email": "test@test.com",
    "status": 1,
    "address1": "Akshya Nagar 1st Block 1st Cross",
    "districtName": "Berkshire",
    "addedDate": "2020-02-01T04:44:54.000Z",
    "lastModified": "2020-02-25T10:30:47.000Z"
    }]

No need for a plugin - filter is already built in to Javascript:
Array.prototype.filter() - JavaScript | MDN[^]

JavaScript

let filteredList = groupsList.filter(obj => moment(obj.lastModified).format('DD-MM-YYYY') === objectReady.lastModified || obj.name.toLowerCase().includes(objectReady.name.toLowerCase()) || Number(obj.groupId) === Number(objectReady.groupId));

Demo[^]

The reason it doesn't appear to be filtering anything out is that all three objects in your sample data match one of the conditions in your filter - specifically, all three have a name which contains the word "health".

Ohky, i got the point. One more doubt,

If i keep the object like...

const objectReady = {
"groupId": "1234",
"name": "",
"addedDate": "01-02-2020",
"lastModified": "25-02-2020"
}
it should jut filter the first object in the array. Instead of returning all thoese three object in an array. How to achive that?

You'll have to change your filter function to account for the empty name:

let filteredList = groupsList.filter(obj => moment(obj.lastModified).format('DD-MM-YYYY') === objectReady.lastModified || (objectReady.name && obj.name.toLowerCase().includes(objectReady.name.toLowerCase())) || Number(obj.groupId) === Number(objectReady.groupId));
