Exploring an array will yield only the initial outcome

I am currently working on a task where I need to search through an array to find specific objects based on their category.

However, when I execute my code, I am only getting one result. In the given example below, there should actually be two results as the cat 2 exists in two of the objects!

Here is the snippet of my code:

var storedArray = [{
"title": "test title 1",
"date_added": "2018-09-26",
"url": "someurl.com",
"filename": "file 1",
"category": "cat 1"
}, {
"title": "test title 2",
"date_added": "2018-10-25",
"url": "someurl.com",
"filename": "file 2",
"category": "cat 2"
},{
"title": "test title 3",
"date_added": "2018-10-25",
"url": "someurl.com",
"filename": "file 3",
"category": "cat 2"
}];

var result = storedArray.find( audio => audio.category === 'cat 2' );

console.log(result);

Can someone help me with this issue? Any advice would be greatly appreciated.

Answer №1

Using Array.prototype.find() Method

When the find() method is utilized, it retrieves the value of the first element in the array that meets the conditions defined by the testing function. If no elements satisfy the condition, undefined is returned.

Understanding Array.prototype.filter()

The filter() method generates a new array containing all elements that successfully pass the test set by the provided function.

To achieve the desired outcome as indicated above, it is essential to implement the filter() method:

var storedArray = [{
"title": "test title 1",
"date_added": "2018-09-26",
"url": "someurl.com",
"filename": "file 1",
"category": "cat 1"
}, {
"title": "test title 2",
"date_added": "2018-10-25",
"url": "someurl.com",
"filename": "file 2",
"category": "cat 2"
},{
"title": "test title 3",
"date_added": "2018-10-25",
"url": "someurl.com",
"filename": "file 3",
"category": "cat 2"
}];

var result = storedArray.filter( audio => audio.category === 'cat 2' );

console.log(result);

Answer №3

The ideal solution is to employ the filter function.

Answer №4

According to the MDN guide for locate...

The find() function gives back the initial element's value in the array that fulfills the specified test condition. If not found, it returns undefined.

Main term: primary.

Answer №5

By utilizing the `.find()` method, you are only retrieving the initial record that fulfills the criteria, leading to a single result being returned.
