What is the advantage of creating instances from a method rather than constructor?
Take the newly [`Temporal.PlainDate`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainDate) class as an example. New instances can be created via the constructor: ```js new Temporal.PlainDate(year, month, day) new Temporal.PlainDate(year, month, day, calendar) ``` or via the [`from()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Temporal/PlainDate/from) method: ```js Temporal.PlainDate.from(info) Temporal.PlainDate.from(info, options) ``` I can see that the arguments are different, but one can make the constructor accept both types. So why isn't it the case? Why having a separate method to create new instances?
