writable jsdoc @param not optional

[btakita]

In Webstorm, there is a warning Invalid number of arguments, expected 1..2 for the following.

const store = writable()

The jsdoc definition for writable,

/**
 * Create a `Writable` store that allows both updating and reading by subscription.
 * @param value initial value
 * @param start start and stop notifications for subscriptions
 */

should be

/**
 * Create a `Writable` store that allows both updating and reading by subscription.
 * @param [value] initial value
 * @param [start] start and stop notifications for subscriptions
 */

to indicate that value & start are optional arguments.
