Get Javascript Object from Array of Objects by Value of Property

Get JavaScript object from array of objects by value of property

Working with arrays of objects is a common task in JavaScript development. Often, you may need to find a specific object in the array based on the value of a property. In this blog post, we will explore different solutions to this problem.

Solution 1: Using the find() method

The find() method is a built-in JavaScript function that allows you to find the first element in an array that satisfies a given condition. In our case, we want to find the object with a specific value for a property.

Here’s an example:

const users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Alice' }
];

const user = users.find(obj => obj.name === 'Jane');

console.log(user);

The output of the above code will be:

{ id: 2, name: 'Jane' }

Solution 2: Using a for loop

If you prefer a more traditional approach, you can use a for loop to iterate over the array and check each object’s property value.

Here’s an example:

const users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Alice' }
];

let user = null;

for (let i = 0; i < users.length; i++) {
  if (users[i].name === 'Jane') {
    user = users[i];
    break;
  }
}

console.log(user);

The output of the above code will be the same as the previous solution:

{ id: 2, name: 'Jane' }

Solution 3: Using the filter() method

If you need to find multiple objects that match the given condition, you can use the filter() method. This method creates a new array with all elements that pass the test.

Here's an example:

const users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Alice' },
  { id: 4, name: 'Jane' }
];

const filteredUsers = users.filter(obj => obj.name === 'Jane');

console.log(filteredUsers);

The output of the above code will be:

[
  { id: 2, name: 'Jane' },
  { id: 4, name: 'Jane' }
]

These are three different approaches you can use to get a JavaScript object from an array of objects based on the value of a property. Choose the one that best suits your needs and coding style.

Happy coding!
