Iterate through an array of objects and if a specific property matches a certain condition, extract that particular object - Using

I have an array of objects that I need to iterate through. If a match is found, I want to slice that object.

var object = [
    {
        "Name": 'Kshitij',
        "LastName": 'Rangari',
        "CountryBorn": 'India',
        "CountryStay": 'USA'
    },

    {
        "Name": 'Pratik',
        "LastName": 'Rangari',
        "CountryBorn": 'India',
        "CountryStay": 'Canada'
    },

    {
        "Name": 'Pratibha',
        "LastName": 'Rangari',
        "CountryBorn": 'India',
        "CountryStay": 'India'
    },

    {
        "Name": 'Ankita',
        "LastName": 'Raut',
        "CountryBorn": 'India',
        "CountryStay": 'Australia'
    },

    {
        "Name": 'Wayne',
        "LastName": 'Rooney',
        "CountryBorn": 'UK',
        "CountryStay": 'UK'
    }
]

console.log(object);

object.forEach(function(x){
  if (x.Name==='Kshitij'){

  }
})

object.map(obj => {

    obj.AllFirstName = obj['Name'];
    console.log(obj['AllFirstName']);
})

console.log('------------------------------')

console.log(object);

I need to loop through the objects in the array and remove those with Name === 'Kshitij' and Name ==='Pratik'.

How should I go about achieving this?

Answer №1

If you want to create a new array that filters out certain values based on a specific key in the objects, you can use the following function.

const filterByKey = (key, values) => object => !values.includes(object[key]);

var data = [{ Name: 'John', Age: 25 }, { Name: 'Emily', Age: 30 }, { Name: 'Michael', Age: 28 }];

console.log(data.filter(filterByKey('Age', [25, 30])));
.as-console-wrapper { max-height: 100% !important; top: 0; }

Answer №2

Employ the built-in filtering function to eliminate any elements that meet specific criteria. Subsequently, assign the updated list back to the original object.

const namesToExclude = ['Ethan', 'Liam'];
object = object.filter(item => !namesToExclude.includes(item.Name))

Answer №3

Utilize the filter() method to create a new array without certain objects - view example below:

var people=[{"Name":'John',"LastName":'Doe',"CountryBorn":'USA',"CountryStay":'Canada'},{"Name":'Jane',"LastName":'Smith',"CountryBorn":'UK',"CountryStay":'Australia'},{"Name":'Alice',"LastName":'Johnson',"CountryBorn":'Canada',"CountryStay":'USA'},{"Name":'Bob',"LastName":'Brown',"CountryBorn":'Australia',"CountryStay":'UK'}];

var filteredPeople = people.filter(function(person){
  return person.Name !== 'John' && person.Name !=='Jane'
});

console.log(filteredPeople);
.as-console-wrapper{top:0;max-height:100%!important;}
