Slices

Slices are similar to arrays but are more powerful and flexible.Like arrays, slices are also used to store multiple values of the same type in a single variable. However, unlike arrays, the length of a slice can grow and shrink as you see fit.

• Slices hold references to an underlying array, and if you assign one slice to another, both refer to the same array.

Array vs Slice

Slices:

• Slices are similar to arrays, but are more powerful and flexible.
• Like arrays, slices are also used to store multiple values of the same type in a single variable.
• However, unlike arrays, the length of a slice can grow and shrink as you see fit.

Capacity vs length

• len() function - returns the length of the slice (the number of elements in the slice)
• cap() function - returns the capacity of the slice (the number of elements the slice can grow or shrink to)
