## Usage

```javascript
var replaceAfter = require( '@stdlib/string/base/replace-after' );
```

#### replaceAfter( str, search, replacement, fromIndex )

Replaces the substring after the first occurrence of a specified search string.

```javascript
var out = replaceAfter( 'beep boop', ' ', 'loop', 0 );
// returns 'beep loop'

out = replaceAfter( 'beep boop', 'o', 'bar', 0 );
// returns 'beep bobar'
```

To begin searching from a specific index, provide a corresponding `fromIndex` argument.

```javascript
var out = replaceAfter( 'beep boop beep baz', 'beep', 'foo', 5 );
// return 'beep boop beepfoo'
```

If `fromIndex` is less than zero, the starting index is resolved relative to the last string character, with the last string character corresponding to `fromIndex = -1`.

```javascript
var out = replaceAfter( 'beep boop beep', ' ', 'loop', -6 );
// returns 'beep boop loop'
```

## Notes

-   If a search string is not present in a provided string, the function returns the provided string unchanged.
-   If a search string is an empty string, the function returns the provided string unchanged.
-   If `fromIndex` resolves to an index which is greater than or equal to `str.length`, the function returns the provided string unchanged.
