# camelcase
> Convert a string to camel case.
## Usage

var camelcase = require( '@stdlib/string/camelcase' );
```
#### camelcase( str )
Converts a string to camel case.
```javascript
var out = camelcase( 'foo bar' );
// returns 'fooBar'
out = camelcase( 'IS_MOBILE' );
// returns 'isMobile'
out = camelcase( 'Hello World!' );
// returns 'helloWorld'
out = camelcase( '--foo-bar--' );
// returns 'fooBar'
```
## Examples
```javascript
var camelcase = require( '@stdlib/string/camelcase' );
var str = 'Hello World!';
var out = camelcase( str );
// returns 'helloWorld'
str = 'HELLO WORLD!';
out = camelcase( str );
// returns 'helloWorld'
str = 'To be, or not to be: that is the question.';
out = camelcase( str );

```

## CLI
### Usage
```text
Usage: camelcase [options] []
Options:
-h, --help Print this message.
-V, --version Print the package version.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
```
### 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\nfoo_bar' | camelcase --split /\r?\n/
# Escaped...
$ echo -n $'beep\nfoo_bar' | camelcase --split /\\r?\\n/
```
- The implementation ignores trailing delimiters.
### Examples
```bash
$ camelcase 'hello world!'
helloWorld
```
To use as a [standard stream][standard-streams],
```bash
$ echo -n 'beEp booP' | camelcase
beEpBooP
```
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\nfoo_bar' | camelcase --split '\t'
beep
fooBar
```
