Explain how slices are internally represented in Go.
- Slices are represented as arrays in Go.
- Slices are implemented as linked lists in Go.
- Slices are backed by arrays and include metadata.
- Slices are implemented as dictionaries in Go.
In Go, slices are internally represented as a data structure that includes metadata about the underlying array. Slices contain a pointer to the first element of the array, the length (number of elements in the slice), and the capacity (maximum number of elements the slice can hold without reallocation). This representation allows slices to efficiently work with subarrays of the underlying array without copying data. Understanding this internal representation is essential for effectively working with slices in Go.
