# define-data-property <sup>[![Version Badge][npm-version-svg]][package-url]</sup>

Define a data property on an object. Will fall back to assignment in an engine without descriptors.
The three `non*` argument can also be passed `null`, which will use the existing state if available.
The `loose` argument will mean that if you attempt to set a non-normal data property, in an environment without descriptor support, it will fall back to normal assignment.
## Usage
```javascript
var defineDataProperty = require('define-data-property');
var assert = require('assert');
var obj = {};
defineDataProperty(obj, 'key', 'value');
defineDataProperty(
obj,
'key2',
'value',
true, // nonEnumerable, optional
false, // nonWritable, optional
true, // nonConfigurable, optional
false // loose, optional
);
assert.deepEqual(
Object.getOwnPropertyDescriptors(obj),
{
key: {
configurable: true,
enumerable: true,
value: 'value',
writable: true,
},
key2: {
configurable: false,
enumerable: false,
value: 'value',
writable: true,
},
}
);

Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
Existing properties are not overridden. Accepts a map of property names to a predicate that, when true, force-overrides.
## Example
```js
var define = require('define-properties');
var assert = require('assert');
var obj = define({ a: 1, b: 2 }, {
a: 10,
b: 20,
c: 30
});
assert(obj.a === 1);
assert(obj.b === 2);
assert(obj.c === 30);
if (define.supportsDescriptors) {
assert.deepEqual(Object.keys(obj), ['a', 'b']);
assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'c'), {
configurable: true,
enumerable: false,
value: 30,
writable: false
});
}
```
Then, with predicates:
```js
var define = require('define-properties');
var assert = require('assert');
var obj = define({ a: 1, b: 2, c: 3 }, {
a: 10,
b: 20,
c: 30
}, {
a: function () { return false; },
b: function () { return true; }
});
assert(obj.a === 1);
assert(obj.b === 20);
assert(obj.c === 3);
if (define.supportsDescriptors) {
assert.deepEqual(Object.keys(obj), ['a', 'c']);
assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'b'), {
configurable: true,
enumerable: false,
value: 20,
writable: false
});
}
```
