How can I filter an array of objects by specific attributes

Question

With the help of code, can you tell me How I can filter an array of objects by specific attributes?

Answer 1

You can use the filter() method. The filter() method creates a new array with all elements that pass the test implemented by the provided function.

Here's an example of how to filter an array of objects by specific attributes:

const users = [

  { id: 1, name: 'Alice', age: 25 },

  { id: 2, name: 'Bob', age: 30 },

  { id: 3, name: 'Charlie', age: 25 },

  { id: 4, name: 'David', age: 35 }

];

// Filter users by age = 25

const filteredUsers = users.filter(user => user.age === 25);

console.log(filteredUsers);

In this example, the array users is filtered by the age attribute, and only those with age === 25 are included in the filteredUsers array.

You can filter by multiple attributes by combining conditions:

// Filter users by age = 25 and name starts with 'A'

const filteredUsers = users.filter(user => user.age === 25 && user.name.startsWith('A'));

console.log(filteredUsers);

This will return all users who are 25 years old and have a name starting with 'A'.
