By rkatic:

`jQuery.isPlainObject` is unnecessary here - use the faster `jQuery.type( obj ) === "object"`.

Btw.:
Few lines up, there is `typeof v === "object" || jQuery.isArray(v)` that can be simplified to `typeof v === "object"`.

Also, if really wonted, the isPlainObject can be avoided in **.param** too, by replacing `a.jquery && !jQuery.isPlainObject( a )` with `a.jquery && !hasOwn.call( a, "jquery" )`, but this would require `hasOwn = Object.prototype.toString` on the top - so probably not too beneficial considering that isPlainObject is called only once here.

If you want I can make a pull req.
