How to remove item from array using its name / value with JavaScript?

To remove item from array using its name / value with JavaScript, we can use the JavaScript array’s findIndex and splice methods.

For instance, we write:

const countries = [{
    id: 'AF',
    name: 'Afghanistan'
  },
  {
    id: 'AL',
    name: 'Albania'
  },
  {
    id: 'DZ',
    name: 'Algeria'
  }
];

const index = countries.findIndex(c => c.id === 'AF')
countries.splice(index, 1)
console.log(countries)

We call countries.findIndex with a callback that finds the entry with id set to 'AF'.

Then we call splice with the index found and 1 to remove the entry with the given index.

Therefore, countries is now:

[
  {
    "id": "AL",
    "name": "Albania"
  },
  {
    "id": "DZ",
    "name": "Algeria"
  }
]

according to the console log.

Conclusion

To remove item from array using its name / value with JavaScript, we can use the JavaScript array’s findIndex and splice methods.
