Does assigning a type for a variable improve performance?

Question

which is better for performance?

var example_one = 20
var example_two:int = 20

Answer 1

Static typing currently doesn't increase performance. As per the documentation:

In the future, typed GDScript will also increase code performance: Just-In-Time compilation and other compiler improvements are already on the roadmap!

From the looks of it, increases in performance by way of static typing will be in version 4.0 of the engine.

Answer 2

That is what I have been told.
