define-properties

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

1var define = require('define-properties');
2var assert = require('assert');
3
4var obj = define({ a: 1, b: 2 }, {
5	a: 10,
6	b: 20,
7	c: 30
8});
9assert(obj.a === 1);
10assert(obj.b === 2);
11assert(obj.c === 30);
12if (define.supportsDescriptors) {
13	assert.deepEqual(Object.keys(obj), ['a', 'b']);
14	assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'c'), {
15		configurable: true,
16		enumerable: false,
17		value: 30,
18		writable: false
19	});
20}

Then, with predicates:

1var define = require('define-properties');
2var assert = require('assert');
3
4var obj = define({ a: 1, b: 2, c: 3 }, {
5	a: 10,
6	b: 20,
7	c: 30
8}, {
9	a: function () { return false; },
10	b: function () { return true; }
11});
12assert(obj.a === 1);
13assert(obj.b === 20);
14assert(obj.c === 3);
15if (define.supportsDescriptors) {
16	assert.deepEqual(Object.keys(obj), ['a', 'c']);
17	assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'b'), {
18		configurable: true,
19		enumerable: false,
20		value: 20,
21		writable: false
22	});
23}
