 *
 * @param {object} object The object to define the property on.
 * @param {string} key the property name.
 * @param {*} value the property value.
 * @param {*} [aOptions] the property descriptor.
 * @param {boolean} [aOptions.enumerable=false] - Whether the property is enumerable.
 * @param {boolean} [aOptions.configurable=true] - Whether the property is configurable.
 * @param {boolean} [aOptions.writable=true] - Whether the property is writable.
 * @param {function} [aOptions.get] - The getter function.
 * @param {function} [aOptions.set] - The setter function.
 * @returns The object that was passed to the function, with the specified property added or modified.
 *
 * @example

 *
 * @example
 * // Define an enumerable accessor property.
 * defineProperty(myObject, "myAccessorProperty", undefined, {
 *   enumerable: true,
 *   get: function() {
 *     return this._myValue;
 *   },
 *   set: function(newValue) {
 *     this._myValue = newValue;
 *   }
 * });
 *
 * @example
 * // Define a non-enumerable, read-only data property.
 * defineProperty(myObject, "myReadOnlyProperty", "hello", {
 *   writable: false
 * });
 *
 * @example
 * // Define an enumerable, configurable data property.
 * defineProperty(myObject, "myConfigurableProperty", 42, {
