Discuss the performance implications of using slices in Go.

  • Slices are always faster than arrays in Go.
  • Slices have no performance implications.
  • Slices can be slower than arrays in certain cases.
  • Slices are not supported in Go.
Using slices in Go introduces performance considerations. Slices are dynamically sized, which means they involve memory allocation and copying when resized. This can lead to performance overhead compared to arrays, which have a fixed size. However, slices provide flexibility and ease of use, making them suitable for many scenarios where performance is not critical. It's important to understand when to use slices and when to use arrays based on your application's specific requirements.
