@teasource/perspiciatis-facere-impedit

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

var defineDataProperty = require('@teasource/perspiciatis-facere-impedit');
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,
		},
	}
);
