How would you manage memory efficiently when working with large slices?
- By using the make function to preallocate memory and avoid excessive reallocations.
- By setting the slice capacity to zero.
- By using pointers instead of slices.
- By avoiding slices altogether and using arrays.
To manage memory efficiently when working with large slices in Go, you should use the make function to preallocate memory. Preallocating memory ensures that the slice has sufficient capacity to hold the data without needing frequent reallocations, which can be expensive. By specifying the capacity upfront, you reduce memory overhead and the performance impact of resizing the slice as it grows.
