<section class="usage">
## Usage
```javascript
var repeat = require( '@stdlib/string/repeat' );
```
#### repeat( str, n )
Repeats a string `n` times and returns the concatenated result.

// returns 'aaaaa'
str = repeat( '', 100 );

str = repeat( 'beep', 0 );
// returns ''
```

## Examples
<!-- eslint no-undef: "error" -->
```javascript
var round = require( '@stdlib/math/base/special/round' );
var randu = require( '@stdlib/random/base/randu' );
var repeat = require( '@stdlib/string/repeat' );
var str = 'beep';
var n;
var i;
for ( i = 0; i < 100; i++ ) {
n = round( randu()*3.0 );
console.log( repeat( str, n ) );

<section class="notes">
### Notes
- If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is either properly escaped or enclosed in quotes.
```bash
# Not escaped...
$ echo -n $'beep\nboop' | repstr --n 3 --split /\r?\n/
# Escaped...
$ echo -n $'beep\nboop' | repstr --n 3 --split /\\r?\\n/
```
- The implementation ignores trailing delimiters.

<!-- /.notes -->
<section class="examples">
### Examples
```bash
$ repstr beep --n 5
beepbeepbeepbeepbeep
```
To use as a [standard stream][standard-streams],
```bash
$ echo -n $'ab' | repstr --n 3
ababab
```
By default, when used as a [standard stream][standard-streams], the implementation assumes newline-delimited data. To specify an alternative delimiter, set the `split` option.
```bash
$ echo -n $'beep\tboop' | repstr --n 3 --split '\t'
beepbeepbeep
boopboopboop
```
