Does evacuation occur when the map is filled to the limit?

In Go, when working with maps, there is no concept of a 'fill to capacity' in the traditional sense, as maps dynamically grow as new elements are added.

When you add new key-value pairs, the map automatically increases its internal structure to accommodate the new data. Rehashing occurs internally when the map redistributes elements to optimize access and reduce collisions.

Therefore, when elements are added to a map, redistribution (rehashing) occurs, but this is not related to a fixed fill capacity, rather it is part of internal performance optimization mechanisms.

In summary: yes, rehashing occurs, but not due to 'filling to capacity', rather as part of the internal process of managing the size and structure of the map.
