Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.\nExisting properties are not overridden. Accepts a map of property names to a predicate that, when true, force-overrides.\n\n## Example\n\n```js\nvar define = require('define-properties');\nvar assert = require('assert');\n\nvar obj = define({ a: 1, b: 2 }, {\n\ta: 10,\n\tb: 20,\n\tc: 30\n});\nassert(obj.a === 1);\nassert(obj.b === 2);\nassert(obj.c === 30);\nif (define.supportsDescriptors) {\n\tassert.deepEqual(Object.keys(obj), ['a', 'b']);\n\tassert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'c'), {\n\t\tconfigurable: true,\n\t\tenumerable: false,\n\t\tvalue: 30,\n\t\twritable: false\n\t});\n}\n```\n\nThen, with predicates:\n```js\nvar define = require('define-properties');\nvar assert = require('assert');\n\nvar obj = define({ a: 1, b: 2, c: 3 }, {\n\ta: 10,\n\tb: 20,\n\tc: 30\n}, {\n\ta: function () { return false; },\n\tb: function () { return true; }\n});\nassert(obj.a === 1);\nassert(obj.b === 20);\nassert(obj.c === 3);\nif (define.supportsDescriptors) {\n\tassert.deepEqual(Object.keys(obj), ['a', 'c']);\n\tassert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'b'), {\n\t\tconfigurable: true,\n\t\tenumerable: false,\n\t\tvalue: 20,\n\t\twritable: false\n\t});\n}\n```\n\n## Tests\nSimply clone the repo, `npm install`, and run `npm test`\n\n[package-url]: https://npmjs.org/package/define-properties\n[npm-version-svg]: https://versionbadg.es/ljharb/define-properties.svg\n[deps-svg]: https://david-dm.org/ljharb/define-properties.svg\n[deps-url]: https://david-dm.org/ljharb/define-properties\n[dev-deps-svg]: https://david-dm.org/ljharb/define-properties/dev-status.svg\n[dev-deps-url]: https://david-dm.org/ljharb/define-properties#info=devDependencies\n[npm-badge-png]: https://nodei.co/npm/define-properties.png?downloads=true&stars=true\n[license-image]: https://img.shields.io/npm/l/define-properties.svg\n[license-url]: LICENSE\n[downloads-image]: https://img.shields.io/npm/dm/define-properties.svg\n[downloads-url]: https://npm-stat.com/charts.html?package=define-properties\n[codecov-image]: https://codecov.io/gh/ljharb/define-properties/branch/main/graphs/badge.svg\n[codecov-url]: https://app.codecov.io/gh/ljharb/define-properties/\n[actions-image]: https://img.shields.io/endpoint?url=https://github-actions-badge-u3jn4tfpocch.runkit.sh/ljharb/define-properties\n[actions-url]: https://github.com/ljharb/define-properties/actions\n","homepage":"https://github.com/ljharb/define-properties#readme","repository":{"type":"git","url":"git://github.com/ljharb/define-properties.git"},"author":{"name":"Jordan Harband","email":"ljharb@gmail.com"},"bugs":{"url":"https://github.com/ljharb/define-properties/issues"},"license":"MIT","readmeFilename":"README.md"}
