Arrow function is a new ecmascript specification feature available for us.

Arrow Functions are the annomuis functions.

## Example

### Addition with Sum() function

Let’s see how to use arrow Functions with simple examples

Suppose we have a JavaScript function which accept two parameters and return the addition of those numbers.

```
function sum( a, b ) {
return a + b;
}
```

Now let’s use our sum function to get the addition of 10 and 20.

```
let total = sum( 10, 20 );
console.log( total );
// 30
```

#### Comolete Code

```
function sum( a, b ) {
return a + b;
}
let total = sum( 10, 20 );
console.log( total );
// 30
```
