# spreadMap

It works like the `map()` method, but one value is mapped to more values. It is achieved by returning an array of values to spread into the final array from a callback passed to the method.

```

spreadMap(

 (item, index, array) => array

)

```

> As of **ES10** you can use built-in `flatMap()` method instead.

## Example

```

const arr = [1,2,3,4];

const sm = arr.spreadMap(

  x => [x, x**2]

);

console.log(sm);

// [1,1,2,4,3,9,4,16]

```
