# Javascript Array Callback Function Part 3 - FIND METHOD

The next part of the array methods we will be looking at that expects a callback is called 'FIND'. Find does what it sounds like. It finds, retrieves, and returns the value of the **first element** in the array that satisfies the provided testing function. Find returns only one value or element that matches in a given array even if they are several match, it stops after it finds the very first one.

## FIND METHOD SYNTAX

### - Using anynomous function statement
```
  arr.find(function (parameter) {
     return parameter;
})
```
### - Using anynomous arrow function
```
  arr.find( parameter => {
     return parameter
})
```

#### Example 1: We have an array of Developer advocates. Let's find the first author with a 'dev' title.
```
let devAds = [
	'dev. Edidiong Asikpo',
	'dev. Bolaji Ayodeji',
	'dev. Erica Hanson',
	'dev. Stephen Counsellor'
]

// using an implicit return arrow function.

const findDev = devAds.find(devAd => (
	devAd.includes('dev.');
));
console.log(findDev)
OUTPUT
// 'dev. Edidiong Asikpo'
```
To figure out devAds contains the word dev. we use *.includes* method

the** 'return'** function have to return true or false, and first time it returns true for a given devAds array, find is done and it returns the first 'dev.'


#### EXAMPLE 3: Let's also see how find method works on objects using the same object we created in our last episode, but with an added key called 'rating'.
```
const books = [{
	   title: 'Gods are not to blame',
	   author: ['Ola Rotimi'],
	   rating: 4.11
	},
	{
	   title: 'Creating impressive proposals in Open Source Programs',
	   author: ['Edidiong Asikpo'],
	   rating: 4.36
	},
	{
	   title: 'She inspires',
	   author: ['Bolaji Ayodeji', 'Edidiong Asikpo'],
	   rating: 4.15	
	},
	{
	   title: 'javascript Grammer',
	   author: ['javascript Teacher'],
	   rating: 4.91
	}
];

const mostRated = books.find(book => book.rating >= 4.3);

console.log(mostRated)

//OUTPUT
{
 author: Array [ "Edidiong Asikpo" ]
 rating: 4.36
 title: "Creating impressive proposals in Open Source Programs"
}
// Lets find the book authored by Edidiong
const didicodes = books.find(book => (
	book.author.includes('Edidiong Asikpo')
))

console.log(didicodes)
//OUTPUT
{
 author: Array [ "Edidiong Asikpo" ]
 rating: 4.36
 title: "Creating impressive proposals in Open Source Programs"
}
```
