javascript - JsDoc: How do I document that an object can have arbritrary (unknown) properties but with a particular type? -

this similar question 30360391. want express parameter of function plain js object can have arbitrary properties (with unknown) names properties objects fixed properties.

an example: function this

/**  * @param {descriptor} desc  */ function foo( desc ) {   // ... } 

and typical desc looks like

desc = {   unknownentity1: {     priority: 5;     writable: false;   },   unknownentity2: {     priority: 42;     writable: true;   },   unknownentity3: {     priority: 9;     writable: false;   } } 

i have

/**  * @typedef {object} descriptorentry  * @property {number} priority - priority of entity  * @property {boolean} writable - true, if entity can modified  */ 

i still need typedef descriptor express descriptor object arbitrary properties of type descriptorentry. pseudo-code like

/**  * @typedef {object} descriptor  * @property {descriptorentry} *  */ 

of course, asterisk * wildcard "any property" invalid jsdoc syntax. how do correctly?
