In Go (or Golang), a slice is a data structure that provides a more powerful, flexible, and convenient way to work with sequences of elements compared to arrays. A slice is a segment of an array and allows for more dynamic and easier manipulation of collections of data.

Key Features of Slices:
Dynamic Size:

Unlike arrays, slices can grow and shrink in size. This makes them more versatile for handling collections of data whose size may change.
Underlying Array:

A slice is a reference to a segment of an array. The slice itself doesn't store any data; it just describes a section of an underlying array.
Three Properties:

Pointer: Points to the first element of the array that is accessible through the slice.
Length: The number of elements in the slice.
Capacity: The number of elements in the underlying array, counting from the start of the slice.
Zero Value:

The zero value of a slice is nil, which has a length and capacity of 0.
