# xcase
Blazingly fast recursive conversion to and from camelCase or PascalCase for objects and arrays and strings.
It supports both Node.js and Browser.
xcase passes most of https://github.com/domchristie/humps tests, excluding only those with custom regexps and handler functions. So if you use `humps` and need something much faster than this is the right place.

## Installation
Node: `npm install --save xcase`
Browser (JSPM): `jspm install npm:xcase`
Browser (Bower): `jspm install xcase`
Browser (Manual): Load https://raw.githubusercontent.com/encharm/xcase/master/dist/xcase.min.js and use global `xcase` object
## Usage:
```
let {camelizeKeys} = require('xcase');
let obj = camelizeKeys({
foo_bar: 1
});
// obj is {fooBar: 1}
```
## API
* `camelize(string, [options])`
change `"foo_bar"`/`"foo bar"`/`"foo-bar"` to `"fooBar"`
* `camelizeKeys(objectOrArray, [options])`
change all keys according to `camelize`
* `decamelize(string, [options])`
change `"fooBar"` to `"foo_bar"` and takes custom `separator` in options
* `decamelizeKeys(objectOrArray, [options])`
change all keys according to `decamelize`
* `pascalize(string, [opts])`
change `"foo_bar"`/`"foo bar"`/`"foo-bar"` to `"FooBar"`
* `pascalizeKeys(objectOrArray, [options])`
change all keys according to `pascalize`
* `depascalize(string, [opts])`
change `"FooBar"` to `"foo_bar"` and takes custom `separator` in options
* `depascalizeKeys(objectOrArray, [options])`
change all keys according to `depascalize`
Options:
* `inPlace: true` - to modify existing object (note, it's slower than default! v8 is smarter than us)
* `separator` - for example `-` for `de**` variant of functions
