# uncapitalizeKeys
> Convert the first letter of each object key to lowercase.
## Usage
```javascript
var uncapitalizeKeys = require( '@stdlib/utils/uncapitalize-keys' );
```
#### uncapitalizeKeys( obj )
Converts the first letter of each `object` key to lowercase, mapping the transformed keys to a new `object` having the same values.
```javascript
var obj1 = {
'BeepBoop': 1,
'FooBar': 2
};
var obj2 = uncapitalizeKeys( obj1 );
// returns { 'beepBoop': 1, 'fooBar': 2 }
```
## Notes
- The function only transforms **own** properties. Hence, the function does **not** transform inherited properties.
- The function **shallow** copies key values.
## Examples
```javascript
var uncapitalizeKeys = require( '@stdlib/utils/uncapitalize-keys' );
var obj1 = {
'AA': 'beep',
'BB': 'boop',
'CC': 'foo',
'DD': 'bar'
};
var obj2 = uncapitalizeKeys( obj1 );
console.dir( obj2 );
// => { 'aA': 'beep', 'bB': 'boop', 'cC': 'foo', 'dD': 'bar' }
```
