Is There a More Idiomatic Way to Copy Map Elements in Go?

Copying Map Elements: Exploring Alternative Approaches

Given two maps, dst and src, the common approach to copy all entries from src to dst involves a for-range loop as follows:

for k, v := range src {
    dst[k] = v
}

However, some may question if there exists a more idiomatic solution for this task.

The answer provided suggests that the aforementioned approach is adequate. The use of a for-range loop offers a clear and concise way to iterate over the elements of src and assign them to dst.

Nevertheless, it is important to note that there is no dedicated one-liner solution in Go for copying maps. The copy function, which is commonly used to copy slices, does not support copying maps directly.

Therefore, for scenarios where you need to copy map elements, the for-range loop approach remains a reliable and effective option.
