JavaScript find() method

Today we are exploring the find() array method in JavaScript.
I find this method very similar to the some() method.

What it does is it searches the array for a specific hit, but instead of returning a boolean, it will return the first match it finds.

Using the Javascript find() method

Let's start by creating an array of items.

const items = [
  { name: 'T-shirt plain', price: 9 },
  { name: 'T-shirt print', price: 20 },
  { name: 'Jeans', price: 30 },
  { name: 'Cap', price: 5 }
];

Let's find the first item that is under the price of 10.

const haveNames = items.find(item => {
  return item.price < 10;
});

// { name: 'T-shirt plain', price: 9 }

This can also be written as a one-liner:

const found = items.find(item => item.price < 10);

Some use cases could be the first blog-post with the same category.

To see this in action let's say we are currently viewing this article:

const blog = {
    'name': 'JavaScript find() method',
    'category': 'javascript'
}

And we have an array of blog items like this:

const blogs = [
  {
    'name': 'CSS :focus-within',
      'category': 'css'
  },
  {
    'name': 'JavaScript is awesome',
      'category': 'javascript'
  },
  {
    'name': 'Angular 10 routing',
      'category': 'angular'
  }
];

Now we can use find() to get the first blog item that is related to our one (javascript based).

const related = blogs.find(item => item.category === blog.category);
console.log(related);

// { name: 'JavaScript is awesome', category: 'javascript' }

There you go, an example of how to use the find find() method in JavaScript.
