Auto-detection

Anything that isn't found to be a class, method, event or config, is treated as property. So often the @property tag is not even needed as it's the default. The following is equivalent of the above:

/**
 * True when panel is hidden.
 */
Ext.Panel.prototype.hidden = false;

Here the name (hidden), type (Boolean) and default value (false) of the property are all auto-detected.

Here we use the @property tag to force JSDuck to treat BASE_URL as a property (otherwise it will think it is a class name becase it begins with an uppercase letter):

/**
 * @property
 * Base URL to use for Ajax requests.
 */
Ext.Ajax.BASE_URL = "/";

JsDuck will auto-detect Number, String, Boolean, RegExp and Function types when it sees the corresponding literal assigned to the property. Also arrays of these literals will also detected:

/**
 * CSS class names to apply for root element.
 */
cls: ["x-component", "x-item"],

Here the cls property will be detected with type String[].

With anything else the type will default to Object.

All the above also applies for detecting default values. To avoid auto-detection of default value specify undefined as the default:

/**
 * @property {String} [baseName=undefined]
 */
baseName: "foo",
