What happens if a slice exceeds its capacity while appending elements in Go?
- A new underlying array is allocated, and elements are copied over.
- An error is thrown.
- Elements are automatically truncated to fit the capacity.
- It leads to a runtime panic.
In Go, if a slice exceeds its capacity while appending elements, a new underlying array with a larger capacity is allocated, and the existing elements are copied over. This ensures that the slice can accommodate the new elements without causing a runtime error.
